FAQs
How is my exact age calculated?
We compare your date of birth with the selected date and compute full years first, then the remaining months and days, accounting for different month lengths and leap years.
Can I calculate age on a future or past date?
Yes. Change the “age at” date to any date to find your age on that day — useful for exam cut-off dates and form deadlines.
Does it handle leap years?
Yes. The calculation uses real calendar dates, so February 29 and leap years are handled correctly.
Is my date of birth stored?
No. The calculation happens entirely in your browser and nothing is uploaded or saved.
