How to calculate your exact age

Enter your date of birth in DD-MM-YYYY format and tap Calculate My Age. This free online age calculator compares your birth date with today's date and shows your exact age in years, months and days, along with total days and full weeks. It also works as a chronological age calculator, helping you find your completed age on a chosen date.

Find your birth weekday and date history

The result also tells you the day of the week you were born. The “What Happened on Your Date?” feature looks for historical events recorded for the same day, month and birth year. If no matching event is available, that does not mean nothing happened; historical databases can be incomplete. Events from other years are labelled separately.
