How to calculate your exact age
Enter your date of birth and, if you want your age as of a specific date rather than today, change the second date. The calculator accounts for varying month lengths and leap years, so the years/months/days breakdown is always exact.
Why total days and weeks matter
Some forms and eligibility checks (age limits for exams, minimum age requirements, insurance applications) ask for age in total days or completed months rather than the usual years/months/days — this tool shows both at once.
Is my birth date stored anywhere?
No. The calculation happens entirely in your browser using JavaScript — nothing is sent to a server or saved.
