These calculators help you work with calendar dates: calculate an exact age, find a date after adding or subtracting time, or compare the gap between two dates of birth. They account for real month lengths and leap years.
Age Calculator: See your age today and find out when your next birthday arrives.
Date Calculator: Move a date forward or backward by a chosen number of years, months, weeks or days.
Age Difference Calculator: Compare two dates of birth and see the difference in years, months, days, weeks and total days.
All three calculators show step-by-step working. Dates are handled according to each calculator's documented rules, including February 29 in non-leap years.
