China Business Days: Delivery Dates and Make-up Weekends

A supplier's promise of “five working days” cannot be converted reliably by counting Monday through Friday alone. Mainland China's annual holiday arrangements can designate a weekend as a workday and combine weekday holidays with adjoining days off. The supplier may also operate its own production calendar.

Separate the counting rule from the promise itself. A calendar can calculate the result once the rule is clear; it cannot decide whether the supplier meant five days after payment, after sample approval or after production materials arrive.

Set the starting event

Write down the trigger and its local date. For example, “payment confirmed before the supplier's stated cut-off on Friday” is more precise than “paid Friday”. Time-zone differences, a payment review or a daily cut-off can move the effective starting date.

Then decide whether that starting date counts as day one. An operation that adds working days commonly begins counting on the following date. A date-range report may instead include both endpoints. These methods answer different questions and should not be mixed.

A weekend that changes the answer

Under the published mainland schedule for 2026, New Year's leave runs from January 1 through January 3, while January 4, a Sunday, is an adjusted workday. Count the inclusive interval from January 1 through January 5: it contains five calendar days but two scheduled working days, January 4 and January 5.

Suppose a job starts on January 4 and requires two working days after that start date. Excluding the start, the counted days are January 5 and January 6. If the contract counts the start as the first working day, the second day is instead January 5. The one-day difference comes from the agreement, not an arithmetic fault.

Ask for the relevant calendar

• Calendar days: count consecutive dates, including weekends and holidays.
• Official scheduled working days: use the published mainland holiday and make-up schedule for the relevant year.
• Supplier production days: use the factory's confirmed closures and operating days.
• Transit days: use the carrier's service definition and route-specific schedule.

A factory closure around a holiday can be longer than the official public holiday. Conversely, a retailer or transport service may continue operating. Customs processing and international transit can involve additional calendars. Do not replace all of them with one mainland working-day total.

Separate processing from delivery

A purchase can pass through several stages with different starting events. The seller may need working days to confirm artwork, prepare goods and hand the parcel to a carrier. The carrier then applies its own transit definition. An estimate described as “three days processing plus five days delivery” is incomplete until you know whether both stages use calendar days or their own working-day schedules.

Do not begin the second stage merely because the first stage's estimated date has arrived. If dispatch actually takes place later, the carrier's counting trigger may also move. A shipment record should distinguish the planned dispatch date, actual acceptance by the carrier and expected arrival. A calendar result is useful for planning; it is not evidence that a handover has happened.

Suppose a supplier says a parcel will be “ready in five working days” after sample approval. That wording concerns preparation. It does not automatically include collection or arrival at your premises. Confirm the event you need: goods ready for collection, handed to the carrier, or delivered. Then ask for the corresponding date in writing.

Make an illustrative order record

For a simple example using the official 2026 calendar, record an acceptance date of September 18, a period of five working days and a rule excluding the acceptance date. September 20 is an adjusted Sunday workday, so the five counted dates are September 20, 21, 22, 23 and 24. The resulting completion date is September 24.

This is a made-up planning example, not a supplier service promise. If the supplier does not work on September 20, replace the assumption with its actual operating calendar. Keeping the assumption visible makes the difference explainable instead of leaving two people with conflicting dates and no record of how either was calculated.

Keep updates attached to the trigger

If approval arrives late or the order changes, check whether the agreed starting event has moved. Do not silently add a buffer to the old result while leaving the original trigger unchanged. Ask the supplier which date now counts as the start and whether the original duration still applies.

A buffer can be useful for your own planning, but it is separate from the supplier's stated deadline. For example, you may choose an internal check-in before the promised completion date. Label that as your check-in rather than presenting it as a revised commitment from the supplier.

When the order crosses a holiday period, confirm the people and services needed for each stage. A production team, an office approving paperwork and a collection service may not resume together. One extra sentence specifying the handover event often resolves more uncertainty than a detailed countdown based on the wrong calendar.

Record a date that can be reproduced

Use the China working-day calculator after choosing the start and endpoint rules. Review any holiday or adjusted weekend in the annual calendar. For an interval crossing New Year, both years need published calendar data; do not guess the next year's adjusted weekends.

Keep the agreed start, day count, inclusion rule and resulting date together in the order record. This article concerns delivery planning. A statutory or contractual deadline may prescribe its own counting rule, which must be checked for that specific deadline.
