FAQ
How accurate is this age calculator?
It calculates exact age down to the day, accounting for varying month lengths and leap years.
Can I calculate age at a specific date?
Yes. Change the 'Age at Date' field to any date to see how old you were (or will be) on that day.
How are months with different lengths handled?
The calculator uses calendar-accurate logic. If you were born on Jan 31 and it's Feb 28, it correctly counts one full month.
Is my date of birth stored?
No. Everything runs in your browser. No data is sent to any server.
