About this calculator
An age in completed years hides the months and days. Forms, tickets, and school records sometimes want the fuller count. This calculator takes two dates and reports completed years, completed months, and the remaining days, plus the total number of days and the next birthday.
It uses the calendar. A year is not forced into 365 days, so a leap day stays a leap day.
The second date can be today or any other day. That is useful when a form says “age as on 1 April” rather than age today.
Nothing is stored. The dates stay in the browser unless JavaScript is off, in which case the server works them out and does not keep them.
How age is counted
The count walks from the date of birth to the chosen date. Years are completed years. Months are completed months after that. Days are the days left over. If the day of the month has not been reached, one month is borrowed.
Example
Someone born on 15 August 1995 is 31 years, 1 month, and 20 days old on 5 October 2026.
The next birthday after that date is 15 August 2027.
Born 15 August 1995
Age on 5 October 2026.
31 years, 1 month, 20 days
How to use
- Enter the date of birth.
- Enter the date you want the age on. Today is filled in.
- Press Calculate.
Important notes
- The count uses calendar dates, not a fixed 365-day year.
- A birthday that falls on 29 February is handled by the calendar for the next birthday.
- This is not a legal age certificate.
FAQ
Does it count the birthday itself?
On the birthday the completed years increase and the months and days are zero.
Can the second date be in the past?
Yes, as long as it is not before the date of birth. Use it for “age as on” a form date.
Why might another site differ by one day?
Some sites count the end date and some do not, or they use a 30-day month. This one uses the calendar difference.
