How Date Difference Calculator helps

Choose start and end dates for an accurate calendar-day difference without time-zone drift.

Method and assumptions

Dates are interpreted as calendar days using UTC midnight, so daylight saving does not change the answer.

Example

From January 1 to January 8 there are 7 elapsed days, or 8 dates when counting inclusively.

Know the limits

Check your inputs and verify important financial, health, legal, educational or property decisions using the relevant professional or official source. Results depend on stated assumptions.
