Frequently Asked Questions
How is the exact age calculated?
The calculator computes the difference between your date of birth and today (or a custom date) in years, months, and days, accounting for varying month lengths and leap years.
What additional info do I get?
Besides your exact age, you see total days lived, day of the week you were born, your zodiac sign, and how many days until your next birthday.
Can I calculate age on a specific date?
Yes. By default the calculator uses today's date, but you can set a custom 'as of' date to calculate your age on any past or future date.
