Can a non-Saturday-Sunday weekend be used?

Yes, check whichever days count as the weekend for a given region or industry, since not every convention follows Saturday and Sunday.

Does the count change for a leap-year February?

Yes, a leap-year February has 29 days rather than 28, so the weekday counts no longer split into an exact multiple of full weeks the way a common-year February does.

Worked example

February 2027 has exactly 4 of each weekday, since it runs exactly 28 days, 4 full weeks, and is not a leap year. With a standard Saturday-Sunday weekend, that comes to 20 weekdays and 8 weekend days. Check February 2028, a leap year with 29 days, instead, and the count no longer splits evenly, since that extra day pushes one weekday to 5 occurrences while the rest stay at 4.

Common mistakes

Assuming every February behaves the same way. A leap-year February adds one extra day, breaking the clean 4-of-each-weekday pattern a common year produces.
Forgetting to adjust the weekend definition for a region that does not use Saturday and Sunday. The checkboxes need to match whichever days actually count as off days.

Limitations

This counts weekday composition only. It does not exclude public holidays, so Business Days & Work Calendar should be used instead for a holiday-aware count.
