Business days here means Monday through Friday. The page moves forward or backward by the count you enter and skips Saturday and Sunday. The result shows the landing weekday, how many calendar days the span covered, and how many weekend days were skipped.
A count that should include weekends belongs on the Date Calculator. Hours inside a workday belong on the Work Hours Calculator.
Only Saturday and Sunday are skipped
There is no holiday list. A public holiday that falls on a Wednesday is still counted as a business day. The weekend count in the result is the number of Saturdays and Sundays the walk passed, not a list of named holidays.
Ten business days is not ten calendar days
Starting Tuesday 11 August 2026, ten business days land on Tuesday 25 August 2026. The calendar span is 14 days because two weekends, four weekend days, sit inside it.
Worked example: 10 business days after 11 August 2026
Start on Tuesday, 2026-08-11 and add 10 business days. The result is Tuesday, 2026-08-25. Calendar days spanned: 14. Weekend days skipped: 4. No public holiday was removed.
\[ 10\,\mathrm{weekdays}=14\,\mathrm{calendar\ days} \]
Frequently asked questions
Are public holidays removed?
No. Only Saturday and Sunday are skipped. A holiday on a weekday still counts.
Why is 10 business days equal to 14 calendar days here?
The span from 11 August 2026 to 25 August 2026 contains four weekend days, so the calendar length is longer than the weekday count.
Can I count backward?
Yes. A negative business-day count walks backward and still skips Saturday and Sunday.
Does the start day itself count as day 1?
No. The walk starts on the next weekday. The start date is the day you begin from, not the first counted day.
What if I need every calendar day?
Use the Date Calculator. This page will not include Saturday and Sunday in the count.

Assumptions and limitations
Only Saturday and Sunday are skipped. There is no country holiday pack, and a weekday public holiday is still counted.
