Days Between Dates Calculator
Count the number of days between two dates, shown as days and as weeks plus days.
Days Between Dates
What This Calculator Does
Counting the days between two dates by hand is fiddly - months have different lengths and leap years sneak in an extra day - so it is easy to be off by one. This tool counts the exact number of days from the start date to the end date, and also breaks it into weeks plus leftover days.
How to Use It
- Choose the start date and the end date.
- Read the number of days (and the weeks-plus-days breakdown).
The order does not matter — the result is the same number of days either way.
Worked Examples
| Start | End | Days |
|---|---|---|
| 2026-01-01 | 2026-12-31 | 364 |
| 2024-01-01 | 2024-12-31 | 365 |
| 2026-01-01 | 2026-02-01 | 31 |
| 2026-03-01 | 2026-03-15 | 14 |
(2024 has 366 days because it is a leap year, so January 1 to December 31 is 365 days apart.)
FAQ
How do you count the days between two dates?
Subtract the earlier date from the later one. This tool gives the absolute difference, so the order you enter them does not change the result.
Does it include both the start and end dates?
It counts the difference between them (the number of days from one to the other), not an inclusive count of both endpoints.
How many weeks is that?
The steps show the total days as weeks plus any leftover days — for example, 364 days is 52 weeks and 0 days.
Does it handle leap years?
Yes. The dates are compared directly, so leap days are included automatically.
