🎂 Age Calculator — Exact Age in Years, Months & Days
Exact age from date of birth — years, months, days.
Select your date of birth and find your exact age — in years, months and days, total days lived, and how many days are left until your next birthday.
How to Use?
- Select your date of birth.
- Press Calculate.
- See your exact age and next birthday countdown.
How Is Age Calculated?
Subtracting the date of birth from today's date gives years, then the remaining months and days — accounting for leap years.
Frequently Asked Questions
Does it show exact age?
Yes — by year, month and day, including leap years.
What is the next birthday countdown?
It also tells you how many days are left until your next birthday.
Why no future date?
A future date would give a negative age, so it is not allowed.
