Date Calculator
Find days between two dates, or add/subtract time from a date
Frequently Asked Questions
Enter both dates in the 'Days Between Dates' tab. The calculator subtracts one date from the other and shows the result in days, weeks, and months.
Use the 'Add/Subtract' tab, enter a starting date, and enter how many days, weeks, months, or years to add or subtract.
This calculator counts the number of full days between the two dates (exclusive of the start date, inclusive of the end date) — the standard way most date-difference tools measure elapsed time.
