Step-by-step instructions (English)
- Enter the starting date and how many business days to move forward or backward.
- Choose working weekdays and enter holidays that should not count.
- Calculate the destination date and check it against your required deadline convention.
計算式と方法
Move forward or backward one date at a time and count only selected weekdays that are not holidays. The starting date is excluded from the count. Zero business days leaves the starting date unchanged, even on a weekend.
使用例
Starting on Friday and adding one business day with a Monday–Friday schedule returns Monday, unless Monday is a listed holiday.
When this tool is useful
Estimate delivery dates, review task deadlines, or schedule follow-ups using a known working calendar. This is particularly helpful when a public holiday interrupts a normal workweek.
Common mistakes and limitations
- The starting date is excluded, so adding one business day starts counting from the next date.
- Business deadlines may also have cut-off times or special rules that a date-only calculation cannot apply.
Practical questions about this tool (English)
What happens when I add zero business days?
The original date is returned unchanged, including when it falls on a weekend or holiday. Zero is not treated as an instruction to move to the next workday.
Can I use a Sunday-to-Thursday workweek?
Yes. Select the weekdays that apply and enter the relevant holidays. The result follows your selected schedule rather than a country-wide holiday database.
