Date & Time Calculators & Tools

Forms, exams, job applications and government schemes often ask for your exact age on a specific date, not just your birth year. These calculators do the calendar arithmetic correctly, including leap years and month lengths, so you do not have to count on your fingers.

The age calculator tells you your age in years, months and days on any date, plus the total number of days, weeks and hours you have lived and how many days remain until your next birthday. Everything runs in your browser and no dates are stored.
