IAS Hindu Age Calculator
Some aspirants use traditional or Hindu calendars for age determination, but for UPSC, only the Gregorian calendar (as per DOB in official documents) is valid. The IAS Hindu Age Calculator may serve personal purposes, but it is not acceptable in official calculations.
Age Calculator Hijri to Gregorian
If you’re using the Hijri calendar, you must convert your birthdate to the Gregorian calendar using a Hijri to Gregorian age calculator. UPSC accepts only dates based on the Gregorian system.
Your Age in Hijri vs UPSC Eligibility
Knowing your age in the Hijri calendar can be useful, but keep in mind:
UPSC calculates age on August 1st of the exam year, as per the Gregorian date of birth.
How the Age Limit is Calculated for UPSC
Let’s clarify how the age limit is calculated for UPSC:
- Count your age from your DOB to August 1st of the target exam year
- This age determines whether you fall between 21 and the upper limit for your category.
- Even one day less/more could affect eligibility
UPSC IAS Attempt Limits
Not only ag,e but the number of attempts is also capped:
| Category | Attempts | Age Limit |
| General / EWS | 6 | 32 Years |
| OBC | 9 | 35 Years |
| SC/ST | Unlimited | 37 Years |
| PwBD | Depends on the category age limit |
So even if you’re within the age limit, exceeding attempt limits will disqualify you.
