Calendar Composition Calculator

Count how many weekdays and weekend days a month contains, with a custom weekend definition if your week doesn't run Saturday-Sunday.

Need to also exclude holidays? See Business Days & Work Calendar.

Worked example

February 2027 has exactly 4 of each weekday, since it's exactly 28 days (4 full weeks) and not a leap year. With a standard Saturday-Sunday weekend, that's 20 weekdays and 8 weekend days.

Limitations

This counts weekday composition only; it does not exclude public holidays. See Business Days & Work Calendar for holiday-aware counts.

Frequently asked questions

Can I use a non-Saturday/Sunday weekend?: Yes, check whichever days you consider the weekend; some regions and industries use a different pattern.
