The gap in plain numbers

From Thursday, January 1, 2026 to Saturday, January 31, 2026 is 30 days. That is 4 full weeks and 2 extra days, or 0 years, 0 months and 30 days if you count in calendar units. In hours the span is 720, and in minutes 43,200. The calculation counts midnight to midnight, so the start day is left out and the end day is counted.

Working days and weekends

Inside the range there are 21 weekdays from Monday to Friday, 5 Saturdays and 4 Sundays. If you are counting notice periods, delivery windows or billing days, remove public holidays that fall on weekdays to get the number of business days that really count. Over the whole span, roughly 70% of days are weekdays.
