Age & date duration calculator
Find your exact age in years, months and days, or measure the gap between any two dates. The tool also gives the totals in months, weeks, days, hours and minutes, and counts down to the next birthday. It accounts for leap years and different month lengths, so the answer is precise.

Enter your date of birth. The tool shows your age in years, months and days as of today (or any date you choose), plus totals in weeks, days, hours and minutes.
Does it count the days between two dates?
Yes — switch to “Between two dates”, pick a start and end date, and it shows the full duration and the totals.
Does it handle leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are handled correctly.
