Count the days between two dates
Enter a start date and an end date above to find how much time lies between them, shown as days, weeks, months and years. This is useful for counting down to an event, working out project durations, or measuring how long ago something happened. The calculation runs entirely in your browser.
What it counts
The result is the number of whole days between the two dates, then the same span expressed in weeks, months and years for convenience.
Frequently asked questions
Does it count both the start and end day?
It counts the number of days from the start date to the end date, which is the gap between them rather than the days inclusive of both.
Can the dates be in any order?
Yes. The result is the same whichever date you enter first, because it uses the difference between them.
