Your exact age appears here, and updates as you type.
How to use it
Enter your date of birth
Use the date on your matriculation certificate. Your exact age appears immediately, in years, months and days.
Set the crucial date
Change “Age as on” to the date the notification names. This is what decides eligibility — not today's date, and not the date you apply.
Add the post's age limits
Type the minimum and maximum age from the notification. You get a straight answer, the margin you have in days, and the relaxed limit for every category.
Why the crucial date matters more than today’s date
Almost every rejection on age happens for the same reason: the candidate worked out how old they are now, when the notification measures age on a fixed day of its own. A vacancy advertised in October may set its crucial date at 1 August, and three months is the difference between eligible and not for anyone close to the limit.
The date is always in the notification, usually in the eligibility section, worded as “age as on” or as a range of birth dates you must fall between. Put that date into the calculator above and the answer you get is the one the recruiting body will arrive at.
Where this tool and the official notification differ, the notification is right. Check your eligibility against it before you pay any fee — see our disclaimer.
Common questions
How is age calculated for government jobs in India?
Your age is counted as on the crucial date printed in the notification, not the date you apply and not today. That date is often the closing date for applications, but it can be the first day of a month or an entirely separate date, so read the notification rather than assuming. Enter it in the “Age as on” box above and the calculator works to that date.
What is the crucial date in a recruitment notification?
It is the single date on which every candidate's age is measured, so that everyone is judged on the same day regardless of when they applied. A notification will word it as “age as on 01.08.2026” or “candidates must not have been born earlier than…”. If a notification is extended, the crucial date usually does not move with it.
Which date of birth should I use?
The one recorded on your matriculation or secondary school certificate. That is the date recruiting bodies accept, and a date of birth on any other document will not override it. If your certificate and your other records disagree, get it corrected before you apply.
How much age relaxation do SC, ST, OBC and PwBD candidates get?
For most central government direct recruitment, the upper age limit is relaxed by 3 years for OBC (non-creamy layer), 5 years for SC and ST, and 10 years for persons with benchmark disabilities — which stacks on top of the category relaxation, so a PwBD candidate from a scheduled caste may get 15 years. These are the common figures, not a universal rule: individual notifications vary, and ex-servicemen, departmental candidates and widows are counted on different terms again.
I turn the maximum age a few days after the crucial date. Can I still apply?
Yes. Age is measured on the crucial date alone, so if you are within the limit on that day it does not matter that you cross it afterwards. The calculator shows how many days of margin you have, and the exact range of birth dates the limits allow.
Is this calculator official?
No. It is a free tool to save you the arithmetic, and nothing more. The notification you are applying to is the only authority on its own age limits and relaxations — always check your eligibility against it before paying an application fee.
