Days Between Two Dates
Enter a start date and end date to see how many calendar days apart they are. The page also shows whole weeks plus leftover days (for example 45 days as 6 weeks and 3 days). Order does not matter: the count uses the absolute gap.
How to use
Fill in Start date and End date. Read Total days and the weeks/days breakdown under the result card.
Example
From 1 January 2026 to 15 March 2026 you get 73 calendar days, shown as 10 weeks and 3 days. Swap the dates and the count stays the same.
Tips
This is calendar-day math, not business days. For Mon–Fri only counts, use Working days. For adding a length to one date, use Date calculator or Add days.
