Example Calculations for 2026 (Including Leap Year Adjustments)
Let’s calculate business days for February 2026 (leap year):
- February 2026 has 29 days.
- Count how many Saturdays and Sundays in February 2026 and subtract from 29.
- Check if there are any public holidays (like Presidents’ Day, February 16, 2026) and subtract if it lands on a weekday.
- This gives you the total business days in February 2026.
Common Formulas and Shortcuts
- Standard formula: Total days – (Number of Saturdays + Sundays) – Weekday holidays = Business Days
- Shortcut: Most months have about 4 weekends, so subtract 8 for weekends, then subtract holidays.
