Holidays, without a second thought, are the happiest moments embraced globally. Whether it is the young ones, the working class, or different business industries, each of us showcases a situational change during weekends and seasonal vacations.
Logistics and transportation is one such segment to experience the changes during the holidays. Not just the number of orders but also the navigational plans and working schedules require thorough analysis during this phase.
Studies by Salesforce reveal that holidays have a direct impact on purchasing decisions, where retail buyers made 6% higher online sales during the Cyber Week holidays.
Transport companies consider the holiday calendars as an important constraint for the route optimization process, especially during multi-region route planning. It is to note here that America itself follows holiday calendars that vary statewise or regionwise.
Note: Along with the 11 federal holidays, some states in the USA also add state-specific holidays to the list; for example, Cesar Chavez Day in California, Pioneer Day in Utah, etc. On the other hand, Texas, which celebrates Thanksgiving and Christmas as state holidays, does not recognize Columbus Day from the 11 federal holiday list.
Hence, holiday calendars make multi-region route planning a complicated solution. By integrating the NextBillion Route Optimization API, you can leverage the benefits of such off-days to serve maximum delivery orders with the highest quality.
Explaining Multi-region Route Planning in Logistics?
Multi-region route planning in logistics is the process of strategizing an efficient navigational path for delivery vehicles to fulfill hassle-free transportation. These carriers cover several geographical locations spanning different cities, states, or countries and often require timezone-aware logistics knowledge.
It may take from a few days to a few weeks’ time for these trucks to successfully complete the deliveries. These cargo vehicles move long distances, usually covering interstate delivery orders with multiple stoppages on the route.
Note: A vehicle journeying from San Francisco to New York City may take 5-7 days, covering approximately 3000 miles of total distance. But when a cargo truck is transiting on the same route with multiple pickups and dropoffs, it may take 9-12 days to reach the endpoint.
Big business groups in the logistics industry make huge profits by accepting cross-country delivery orders. They utilize the technical resources to manage the vehicle’s capacity, loading/unloading schedules, and other constraints along the way.
Thus, it is essential to pre-plan the delivery route that should be taken by the drivers for timely task completion while keeping it safe and cost-effective. 
Effective multi-region route planning helps logistics companies prevent delays, maximize vehicle utilization, lower operational costs, and deliver a superior customer experience across complex, international supply chains.
What is the significance of multi-region route planning?
Multi-region route planning has huge significance for field service providers when their business area expands in different regions. It creates systematic transit for delivery vehicles and ensures successful interstate deliveries.
- The entire purpose of multi-region route planning is to help the drivers navigate through the most genuine route between the hub and the final destination.
- The genuineness of the route depends on factors such as traffic conditions, weather, delivery schedules, highway tolls, time windows for food, etc. Considering all such factors, the multi-region route planning gives a trusted source of information for the vehicle’s movement.
- With precise route planning in multi-region transportation, the cargo truck drivers do not have to search for better routes to specific destinations. In long-distance delivery scenarios, it saves travelling time and fuel consumption and reduces overall costs.
- The technological advancements have enabled live tracking and real-time traffic data analysis to help the drivers in shipment rerouting with effective decisions.
- The algorithms in powerful route planners have the capability to merge variations of data, such as delivery points, roadblocks, traffic, etc., and create optimized route plans.

Different factors impacting multi-region route planning
Multi-region route planning is composed after considering different elements that affect the movement of the trucks. Some are necessary or beneficial for attaining maximum output from it, while others are unavoidable. Most of such factors directly impact the travel time or cost, while others are thoughtfully included for generating optimized routes and fulfilling delivery task requirements.
Holiday calendars widely impact multi-region route planning, but let us understand in brief the other critical constraints that trigger the process.
Delivery locations: With multiple orders of pickup and drop, it is essential to find a route for trucks where they cover all the spots in a sequence. Route plans ensure the fastest transit with the least repetitive paths.
Time windows: Since these multi-region delivery tasks take a few days for completion, the route plans must consider resting and dining places for the drivers after certain intervals.
Vehicle type: Depending upon the type of load and quantity of orders, the route optimization tool will suggest the vehicle type. Accordingly, it will create a legible route plan that avoids any applicable restriction. The load optimization system will additionally provide instructions to choose a suitable vehicle and adjust the boxes based on the different factors.
Regulations: The state laws often differ from each other and may apply certain restrictions related to the traffic, load limits, and custom checks. The multi-region route plans must follow the local state regulations and include the checkpoints on the path.
Real-time situations: The route planners cannot ignore the weather conditions, traffic congestion, and real-time data analysis for creating the most effective solution.
Holidays: Holidays are prominent factors to consider in the delivery route planning. Some areas in America accept local or regional offs on specific occasions, and such conditions may provoke changes in the movement.
There are many other factors that can affect the multi-region route planning scenario, and with evidence and experience, the delivery managers can assimilate the navigation.
Do Holidays Affect Logistics and Transport Business?
For example, a courier person navigating the route that goes across a school will have to face the crowd during the peak hours of when school ends. In that case, the route plans are automatically optimized for the drivers to take alternative paths. But during vacations, the same route may be considered by the planner due to being a shorter distance than its alternate.
This phenomenal difference gives space to unique activities of celebrations, outings, and online purchases. While at the same time, it also hinders the working capacity in scheduled delivery tasks when not managed properly by the companies. Strategic usage of holiday calendars in route plans serves efficient results and reduces failed delivery attempts.
Here are some common observations during holidays regarding deliveries.
Increased sales: Retail statistics have consistently proved that sales increase during the holiday season. Christmas, Black Friday, or Diwali have dramatically increased the pressure on last-mile delivery services when high influx hits tight deadlines. Companies provoke sales by offering quick deliveries, which enhances customers’ expectations.

Operational hardships: Sudden or scheduled vacations trouble the working patterns of the warehouses, factories, ports, and distribution centers. The delivery process gets delayed due to labor shortages, often during high demands. The end of the festive season has also observed another wave of orders in the form of return gifts, which again requires stringent efforts for timely deliveries.
Navigational issues: While there is an increase in consumer goods purchases during the holiday phase, Americans are always fond of long road trips during weekends and vacations. This often creates a rush on the highways, causing unprecedented traffic delays for the delivery drivers.
Financial disturbances: A significant increase in service demands during specific holiday phases can raise the operational costs. To tackle this problem and bag higher profit margins, companies tend to forecast the demands based on prior data. They can fulfill the stock in the regional hub stations during the holiday season.
Why Should You Consider Holiday Calendars in the USA for Multi-region Route Planning?
Holidays are situational shifts in the regular course of societal and professional schedules. These short or long phases in any part of the country cause significant, region-specific disruptions to the supply chain. Everything gets affected in this period, from delivery timelines and labor availability to transportation costs.
The USA is a vast nation spread across six standard time zones. With strong vibes of being American, people in different states also include culturally significant events as state holidays. Strategizing the multi-region route planning can prove beneficial for logistics companies.
Varying holidays: With no uniformity in regional holidays, a neighboring state to the delivery center might observe a day off for the employees and office. Unplanned traveling to this place can keep the drivers waiting with active backlogs.
Lack of Staff: It is another important aspect of the holidays when the companies need to hire temporary staff to manage off-duty workforce jobs. Cultural holidays statewise can put the warehouses and hubs to work with less capacity. Often drivers from a particular region may apply for a holiday. Route planning in long-haul deliveries must recognize the holiday calendars to manage deliveries according to the working hours.
Quick tips to hire a delivery driver in 2025
Supply chain management: Buyers often make multiple purchases during popular holiday seasons like Thanksgiving and Christmas. This actually creates a gap between the demand and supply, and logistics companies go through hectic schedules to fulfill the cross-country orders. Multi-region route planning serves as a well-crafted solution when holiday calendars are integrated into the tool. Supply chain route optimization ensures successful delivery to the vendors during the open hours in the region.
Customer satisfaction: Inter-regional deliveries are often troublesome during holidays, as the customers track the orders and expect notification about the parcel’s arrival. Multi-region route planning with holiday calendars increases the accuracy of ETAs. The delivery alert system keeps the receiving end ready to take the parcel, and the delivery agents do not have to wait longer.
Traffic delays: Holidays, whether they are state-specific or federal, create traffic congestion on the roads as the residents tend to go out for long trips, jamming the highways. Some occasions, like Mardi Gras in Louisiana, and many others, are celebrated with long parades and celebrations. Hence, awareness of the holiday calendars puts forward optimized multi-region route plans and keeps the transportation task swift through less crowded regions.
Multi-region route planning is thus critical for the drivers to make enlightened and real-time decisions.
What are the key components from holiday calendars that impact multi-region route planning?
Logistics companies look for structured data points in a holiday calendar that are necessary to alter schedules, optimize routes, and adjust delivery flows. These elements affect the load capacity, timing, and compliances across different regions.
Variable dates: Holiday calendars have slight changes each year, and consolidating these dates accurately helps avoid delivery schedules during shutdowns at ports or warehouses.
Operational hours: The working hours at hub stations located across different regions may differ from the standard timings, and even during holidays some centers may allow shortened shifts or half days. Multi-region route plans are adjusted based on this information.
Carrier blackout: Some holidays are mandatory days off for logistics companies in specific regions. Including these dates in the software helps create suitable navigation plans so that shipments do not reach here on a holiday.
Workforce on leave: If the staff members are applying for leave on certain vacation days, then it can be troublesome for the delivery agents to reach them in this period. Multi-region route planning accounts for these details before optimizing the movements.
Restrictions: Road restrictions due to holiday celebrations can disrupt the delivery schedules. In the case of interstate transportation, the cargos are often banned from entering the borders for hours. With prior instructions about the events and closures, the drivers of Moltu-region transit would conveniently bypass the area before the roadblocks.
Likewise, industrial and cultural events in a region may trigger the demands to go higher, but effective tools can anticipate the buying requirements and plan the routes accordingly.

Route Optimization API
It is the primary tool to create the best and most efficient navigation plan for multi-region deliveries. You can add multiple constraints on the platform, which then automatically adjusts the route plan to best fit the requirements of delivery and pickup. Adding holiday calendars with information like shutdowns or roadblocks will help generate a refined path.
While a normal optimization tool would direct the drivers to reach the place from the shortest distance, the NextBillion route planner would consider the holiday closures and avoid those regio-specific dates for the assignment and direct the fleet to another destination with working days.
Driver Assignment API
Once you enter the holiday calendar on the panel, it keeps track of the drivers that can take the fleet to the next destination before the shutdown and assigns the next available driver to join the takeover of the task after pickup or drop-off on the next working day.
It selects the drivers based on the ranking to handle the type of vehicle or specific tasks, along with riding experience, and also adds an alternate person as a backup. This is an essential step in multi-region route planning for successful task completion.
Clustering API
It creates a virtual bundle of orders to be delivered in a particular cluster or area and is specifically useful for favoring holiday calendars disrupting deliveries. Facilitating the tool with the cluster API can strategize a section of deliveries from the cargo to a nearby dropping point and is not scheduled off during the holiday period. 
It will allow the long-haul cargo to move on after delivering the parcels at the point, which can be later delivered as another short delivery assignment through a local vehicle.
Directions API
It can provide accurate directions to the destination between two places and can help the drivers reach the destination in the shortest time possible. It is suitable for avoiding holiday offs in specific regions and keeps the fleet running for multi-region deliveries.
Distance Matrix API:
It can handle a large number of data points to generate distance and accurate ETAs across delivery destinations. The tool can account for historical and real-time traffic details and assist the drivers with the flexibility to choose directions to the delivery points that are not following regional holidays.
Navigation API:
It is an important tool for multi-region route planning that keeps the drivers in the right direction towards the destination. In any situation of a regional holiday falling on the route, this tool will automatically navigate the trucks through an alternate route to avoid congestion.
Constraints like vehicle type, load type, quantity, road restrictions, and other such constraints are considered while giving directions to the drivers.
Route Report API:
Its purpose is to generate a concise report of the movement of cargo trips. The tool plays a critical role in understanding the flaws of multi-region route planning and how the teams can adjust the conditions to make the next assignments more efficient. You will also be able to find out if the drivers followed the instructions of avoiding holiday celebration zones.
Live Tracking API:
Live Tracking API helps monitor and track the movement of cargos while they are on a delivery assignment. The dispatch managers and recipients are always aware of the fleet’s location in real-time and can assist them at any moment of need. If at any point the trucks get stuck due to holiday shutdown or road restrictions, the managers can track them to resume and redesign the assignment. 
Geofence API:
It creates virtual boundaries on the map and helps in controlling the fleet’s movement to not cross the limit or restricted region. For multi-region route planning with holiday calendars as an integral constraint, this API can conveniently keep the trucks away from regions celebrating the festive vacation. Entering these zones would anyways trouble the drivers, who would get stuck in crowds followed by halting positions.
Route Reconstruction API:
It serves the purpose of recreating the route taken by the driver on a past trip and may help in finding a better alternate solution to any issues of delivery faced during the assignment. With holidays as a constraint on multi-region routing, this would help in understanding the situations of particular off days in a region.
Route Dispatch API:
It is a formal way of sharing the route plans, delivery tasks, and other critical details with the drivers. In multi-region route planning, you can add dispatch tasks to the drivers assisting from a halting spot due to weekends or federal holidays off.
Documents API:
It facilitates adding form templates to the delivery tasks and can be accessed by the drivers through an Android or iOS device. The concept is to attach a form as proof of delivery and to take instant signatures online by the client.
This tool increases the work efficiency for the delivery agents. The drivers can hand over the goods to the assigned person at the hub located in the regional holiday zone. The Drivers App allows sharing the authorized proof of delivery document with the dispatch manager.
Maps:
Maps offer multiple functions on the API. It holds pictures detailing the information about specific locations with names of the places and roads. The users get an option for marking geographical regions with vacational offs. The customized image tiles option that zooms in for clarity enhances decision-making and reaching alternate roads during peak hours.
The Road Segment and Road Editor tool allows the dispatch managers to add instructions about speed limits, road restrictions, turns, width, lanes, etc. It serves as additional assistance to the drivers to drive safely and with precision and, thereby, finish the task on time.
Places API:
It gives a searching option to the drivers on the delivery task. They can fetch complete details about the location address, latitude and longitude, landmarks, etc., and this information can be useful for managing deliveries to the facilities having regional closures. The drivers get address-level precision to reschedule the assignment to the active region with no holidays.

FAQs
Multi-region route planning requires precise information about the delivery locations, road network, traffic, and other necessary stoppages. It is beneficial to add operational constraints like holidays that can halt the continuance of transit.
Holiday calendars put forward complete details about the working hours and onsite issues like crowded regions. By integrating this data, you can avoid movement of delivery vehicles to the centers, warehouses, or factories that are supposed to be closed on specific dates. This saves missed deadlines, idle assets, and customer dissatisfaction.
Holidays have a direct impact on the working capacity of an organization, as employees tend to apply for a seasonal off. This shortage of workforce leads to a reduction in services, and companies modify delivery dates to the next possible active hours.
It is possible to avoid order suspension if you integrate holiday calendars into the routing system and accordingly manage the orders with pre-planning and multi-carrier strategies.
While the delivery managers can handle local deliveries during holidays, it becomes hectic and near impossible to manually arrange route plans in multi-region assignments. With chunks of orders to fulfill, which can potentially rise in peak seasons, there is no alternative to integrating a powerful route optimization API with the ERP database.
Tools like NextBillion.ai can automatically manage holiday data, blackout dates, and local operational constraints, enabling dynamic scheduling and efficient rerouting across regions.
Dispatchers from Montana may not be aware of the state holidays of Colorado or Nevada. Some state holidays may have high sentiments among the general public of the region, which can impact the delivery schedules. Hence, integrating holiday calendars can automate the function of arranging deliveries to avoid delays or missing the slots, surcharges, or compliance issues for cross-border operations during the holiday season or peak hours.
Insights from holiday calendars will alert the dispatcher managers at local hub stations to track and stock up the inventory way ahead of the buying season. It is helpful to adapt and integrate holiday calendars and build in extra lead time to account for higher demand, carrier delays, and unpredictable weather or congestion.
Overdependence on a single freight may result in delays due to overloaded road networks or shutdowns. A multi-carrier strategy involves more than one vehicle in the task that may either link in between or be at the hub stations, where nearby orders can be transferred to them. It enhances the flexibility of load management and provides a backup option to reduce the bottlenecks of scheduled deliveries.
NextBillion’s Cluster API and Live Tracking are highly recommended in such situations of segregating the orders and adding multi-carrier features.
