How the arrival date is calculated
Starting from the order date, each following day is checked one at a time. Saturdays and Sundays are skipped; every other day counts toward the business-day total until it reaches the number you entered.
- order date — the date the order was placed
- N — business days needed for delivery
More detail
Why the arrival date can land later than you'd expect
The count only advances on weekdays, so an order placed on a Friday needing 1 business day arrives the following Monday, not Saturday. The more of a weekend the shipping window covers, the further the arrival date shifts from a simple day count.
Tip. If a public holiday falls inside the shipping window, add one extra business day per holiday manually — this calculator only skips weekends.
Frequently asked questions
How is the estimated arrival date calculated?
Starting from the order date, the calculator steps forward one day at a time, skipping Saturdays and Sundays, until it has counted the number of business days you entered — that day is the estimated arrival date.
Does this account for public holidays?
No — it only skips Saturdays and Sundays. Public holidays inside the shipping window aren't subtracted automatically, so add extra days by hand if one falls in the range.
If I order on a Friday and shipping takes 1 business day, when does it arrive?
The next business day after Friday is Monday, since Saturday and Sunday are skipped — enter a Friday order date with 1 business day above to see the same result.
What happens if I enter 0 or a negative number of business days?
The calculator doesn't compute a result for those values — enter a business-day count of 1 or more.
Why does the arrival date sometimes jump by more than a weekend?
Only weekdays count toward the business-day total, so any Saturday or Sunday inside the shipping window adds two extra calendar days without advancing the count — a longer business-day count can span multiple weekends.
