What the results show
- Years, months, and days — your exact age today, counted the calendar-accurate way rather than as a rough decimal.
- Total weeks — the whole number of weeks you have been alive.
- Total days — every day since your birth date, leap days included.
Frequently asked questions
How is my exact age calculated?
It compares your birth date to today's date, borrowing days from the previous month and months from the year where needed — the same way you'd work out an age by hand — so it accounts for months of different lengths and leap years.
Does it count leap years correctly?
Yes. The total-days figure is the real number of days between the two dates, so February 29ths are included automatically.
Why do I see a dash instead of an age?
The date of birth must be a valid date in the past. A future date or an incomplete entry shows a dash until you fix it.
Is my date of birth saved or uploaded?
No. The calculator runs entirely in your browser. Nothing you enter is stored or sent to a server.
