How to Use This Calculator
My Exact Age tab
Select your date of birth using the day, month, and year dropdowns. The calculator instantly shows your exact age in years, months, and days as of today. It also displays your age in total months, total weeks, and total days, along with a countdown to your next birthday.
Age on Date tab
Enter your date of birth and a target date to calculate your exact age on that specific date. This is useful for determining your age on a government exam cutoff date, school admission deadline, insurance application date, or any other reference point.
Govt Job Eligibility tab
Enter your date of birth, select the government exam (UPSC CSE, SSC CGL, IBPS PO, RBI Grade B, or SSC CHSL), and your category (General, OBC, SC/ST, or PwBD). The calculator computes your age on the exam-specific cutoff date and tells you whether you are eligible, how many years of eligibility remain, and the maximum attempts allowed for your category.

The Formula
Age is calculated by finding the difference between the date of birth and the target date in years, months, and days:
Age = Target Date − Date of Birth
Step-by-step:
1. Years = Target Year − Birth Year (adjusted if birthday has not occurred yet)
2. Months = Target Month − Birth Month (adjusted if target day < birth day)
3. Days = Target Day − Birth Day (adjusted using previous month's length if negative)
Total Days:
Total Days = (Target Date − Birth Date) in calendar days
Total Weeks = Total Days ÷ 7
Total Months = (Years × 12) + Months
Government Job Eligibility:
Age on Cutoff = calcAge(DOB, Exam Cutoff Date)
Eligible = (Age ≥ Min Age) AND (Age < Max Age for Category)
Max Age (OBC) = General Max + 3 years
Max Age (SC/ST) = General Max + 5 years
Max Age (PwBD) = General Max + 10 years
Government exams in India use the "as on" concept — your age is evaluated on a specific cutoff date (e.g. 1 August for UPSC, 1 January for SSC), not on the date of application or the exam date. Even a single day over the age limit disqualifies a candidate.
Example
Priya — checking UPSC CSE eligibility (General category)
Priya was born on 15 August 1995. She wants to check if she is eligible for UPSC Civil Services Examination 2026 under the General category. The UPSC CSE cutoff date is 1 August of the exam year.
Step 1: Calculate age on cutoff date
Step 2: Check eligibility
Step 3: Remaining eligibility
Priya is eligible for UPSC CSE 2026 with approximately 1 year of eligibility remaining under the General category. She should plan her remaining attempts carefully. If she had an OBC certificate, her upper age limit would extend to 35 years with 9 attempts.
