Date Difference Calculator
Enter a start date and an end date. The difference updates instantly, in your browser.
How this works
The difference is counted in complete years, months, and days, exactly like an age, but for any two dates. Total days are the calendar days between them, total weeks are whole weeks in that count, and total months are complete months. Dates are handled as local calendar dates, not UTC timestamps, so the result does not shift by a day in different time zones.
