How your age is calculated
The calculator counts whole years from your date of birth, then whole months, then the days left over. Someone born on 15 August 1994 is 32 years, 2 months and 24 days old on 8 November 2026.
Months are counted to the same date each month. If that date doesn’t exist in a month (the 31st in a 30-day month, or 29 February in a normal year), the last day of the month is used instead. Totals in days, weeks and hours count every calendar day between the two dates, including leap days.
Checking your age for an exam or job
Recruitment notices usually set an age limit “as on” a fixed date, such as 1 January or 1 August of the exam year. To check yours:
- Enter your date of birth.
- Change “Age as on” to the cutoff date given in the notification.
- Open “Check an age limit” and enter the minimum and maximum ages.
The result shows whether you are within the limit and the range of birth dates that qualify. Indian exam notices read an upper limit as “must not have reached” that age: for UPSC 2026, “21 to 32 years” means born between 2 August 1994 and 1 August 2005, so someone who is exactly 32 on the cutoff date is not eligible. Confirm the exact wording and any category relaxation in the official notification, or use the ready-made calculators for UPSC, SSC, NDA, CDS and Agniveer.
Birthdays on 29 February
If you were born on 29 February, this calculator treats 28 February as your birthday in years that aren’t leap years. Some countries use 1 March for legal purposes.
Your data stays on your device
Everything is calculated in your browser. Your date of birth is never sent to a server. “Copy link to this result” puts the two dates in the web address, so you can bookmark or share a result if you want to.
COMMON QUESTIONS
Frequently asked questions
Clear answers about this calculator and how to understand its results.
How do I calculate my age from my date of birth?
Enter your date of birth as day, month and year. The calculator shows your age today in completed years, months and days, and your age in total months, weeks, days and hours.
How do I find my age as on a specific date?
Change the “Age as on” date. Use it for exam and job applications that set an age limit on a cutoff date, or to work out how old someone was on a past date.
Does the calculator count leap years?
Yes. Every calendar day between the two dates is counted, including 29 February in leap years.
What if I was born on 29 February?
In years that are not leap years, this calculator treats 28 February as your birthday. Some countries use 1 March for legal purposes, so check the rule that applies to you.
Can I use the result for an application form?
The calculation is exact, but the organisation you are applying to sets the rules. Some count only completed years, and many state the cutoff date and any relaxation in their notification.
Is my date of birth saved anywhere?
No. The calculation runs in your browser and nothing you enter is sent to a server. The “Copy link” button puts the dates in the web address only if you choose to use it.
