The exact gap between two dates
Counting days across months and years by hand is error-prone, especially over a leap year. This calculator gives the precise number of days between any two dates, plus the same span expressed in weeks and as a years-months-days breakdown.
Either order, on your device
Enter the dates in whichever order you like — the result is always positive. It is handy for deadlines, anniversaries, notice periods and project planning, and because it runs locally, the dates you enter stay private.
