For any e-commerce business, delivering orders on time is key to winning customer loyalty, especially during peak seasons. But postal service holidays can cause disruption to even the best-laid planning.
The good news? With a bit of foresight, knowing postal holiday dates ahead, you can ensure you avoid delays.
These are the key mail holidays to take note of, and some best shipping practices to keep things moving smoothly.
Here’s a quick look at some key global postal holidays to watch out for in 2026 and early 2027, plus the typical shipping cut-off deadlines you’ll want to keep in mind.
Date: Friday, December 25, 2026
Christmas is one of the busiest shipping times of the year. Most postal services recommend sending your packages at least one week before Christmas Day or by mid-December to avoid delays for domestic orders, and earlier for international deliveries. For a fuller rundown, see the peak season business checklist.

Following Christmas, many post offices remain closed or operate on limited hours. The good news is that Boxing Day falls right after Christmas, so the same pre-Christmas cut-off should cover it.
Date: Friday, January 1, 2027
New Year’s Day is a public holiday worldwide, and postal services may pause operations around it. Shipping a few days in advance is the safest way to minimise delays.
Date: Saturday, February 6, 2027
Lunar New Year is a major holiday in many Asian countries and often leads to extended postal closures. Send at least a week before, and allow closer to two weeks for shipments heading into mainland China or other markets with extended closures.
Date: Tuesday, March 9, 2027 (dates vary by lunar sighting)
Eid al-Fitr marks the end of Ramadan and is celebrated across many Muslim-majority countries. As with other Islamic calendar dates, the exact day is confirmed closer to the time based on the lunar sighting, so it's worth sending shipments at least a week ahead and confirming local dates nearer the time, since they may shift by a day or two.
Date: Friday, March 26, 2027
Good Friday is a public holiday in many countries. Posting by the Monday or Tuesday of that week is a simple way to avoid the extended weekend closure that follows.
Date: Monday, March 29, 2027
Following Good Friday, Easter Monday closures also affect postal schedules. Since the two holidays fall in the same week, the same pre-Good Friday cut-off will generally cover both.
Date: Saturday, May 1, 2027
Labor Day is widely observed and can disrupt shipping times, especially across Europe and parts of Asia. Sending by the preceding Wednesday or Thursday is a good way to stay ahead of the slowdown.
Shipping in North America means keeping a close eye on these key postal holidays:
Postal services tend to slow down or close entirely on these dates, so aim to send shipments at least three to five business days before the holiday, especially during peak seasons.
South America’s postal calendar includes:
Because holidays differ widely across the region, it's smart to check local post office calendars and send shipments early, usually five or more days before major holidays, to keep deliveries on track. In Brazil specifically, it's worth planning an extra buffer around Carnival week. Post offices technically stay open, but freight and courier networks tend to slow regardless.
Europe’s postal systems observe several major holidays:
Postal cut-offs typically come three to seven days before these holidays, so sending shipments early helps avoid bottlenecks.
It's also worth remembering that UK bank holidays don't always line up with holidays observed across EU member states, so businesses shipping between the UK and the EU should check both calendars rather than assuming one applies to the other. Post-Brexit customs processing can add extra transit days around UK bank holidays too, so it's worth factoring that in when planning cut-offs for UK-EU shipments.
Asia’s mail holidays vary widely but here are the big ones to mark:
Long closures around Lunar New Year and Eid mean shipments should go out at least a week in advance, especially for international deliveries. The same goes for Diwali and Golden Week: both can significantly slow processing and transit, even where post offices themselves stay open.
Australia’s main postal service holidays include:
Postal slowdowns are common around these dates, so it's worth planning shipments three to five business days ahead.
It's also worth remembering that Australia observes both national and state-specific public holidays, and the two don't always line up. A holiday observed in Victoria or Queensland won't necessarily apply in New South Wales or Western Australia, which can shift postal cut-offs depending on where a shipment starts or ends up. For intra-Australia deliveries in particular, checking the relevant state calendar is a safer bet than relying on the national list alone.
Postal holidays across Africa reflect diverse national calendars, but some widely observed include:
Given the range of local holidays, it’s worth checking specific country calendars and sending shipments at least five days before major holidays to avoid delays.
Postal holidays often bring temporary closures or reduced hours at post offices and courier hubs. For businesses, that can mean slower processing, delayed pickups, and longer transit times, and customs clearance can slow down too, adding further lead time to international shipments already caught in the closures.
Especially during peak seasons, these pauses can affect delivery schedules and customer satisfaction if they catch a business off guard, often bringing a spike in customer enquiries as people check on delayed orders. The best way is to anticipate service pauses, plan around peak shipping season, and keep customers informed every step of the way.
With a few smart strategies, you can keep things running smoothly, even during the busiest times.
One of the simplest ways to avoid holiday delays is to send packages ahead of postal cut-off dates. Building in a buffer means less stress, and a far better chance that orders arrive on time.
As a general guide, domestic shipments should go out three to five business days before the holiday, shipments within the same continent need five to seven business days, and intercontinental shipments are best sent seven to 10 business days ahead.
Not every post office follows the same holiday schedule, even within the same country. Some may close for a full day; others might operate on reduced hours. Before shipping, check local post office holiday hours so you can plan drop-offs and pickups accordingly. A quick check can save you from missed dispatches and unexpected delays.
Honesty is the best policy. Let your customers know about potential delays and provide clear delivery cut-off dates upfront. That way, they’re not left guessing, and will appreciate your transparency.
Consider adding a holiday shipping notice to checkout pages, order confirmation emails, and product listings during peak periods helps set this expectation early.
For international orders placed around the holidays, it's worth sharing an estimated delivery date range rather than a specific date, since cross-border transit can be harder to pinpoint during these times.
Consider giving customers choices like expedited shipping, in-store pickup, or scheduled deliveries. Flexibility can help balance demand during postal holidays and improve the overall shopping experience.
Postal holidays and logistics schedules can sometimes change, especially during peak seasons. Keep an eye on DHL’s official service updates so you’re always in the loop and can adjust your plans as needed.
Postal service holidays don't have to disrupt a business. With a bit of planning, deliveries can stay on track even during the busiest seasons. DHL Express makes it even easier, with reliable global shipping, flexible delivery options, and real-time service updates that help businesses stay ahead. So, when the holidays roll around, you’ll be ready to deliver, right on time.
