How to Count Days Between Dates
Subtract the start date from the end date. By default the start date isn’t counted (like counting nights in a hotel stay); choose "include both days" to count every calendar day.
Days = end − start (+ 1 to include both) Weeks = days ÷ 7

Tips
Weekdays here are Monday through Friday with no holidays removed; the business days calculator can skip US federal holidays. Time zones and daylight saving time don’t affect whole-day counts on this page.
