How Exact Age is Calculated
Age calculation considers year, month, and day differences from your date of birth to today. It accounts for varying month lengths and leap years for precision.
Why Exact Age Matters
- Government Documents: Passport, Aadhaar, voter ID require exact DOB
- School Admission: Age cutoff dates vary by state and board
- Job Applications: Upper age limits for government exams (UPSC, SSC, Banking)
- Insurance & Retirement: Premium calculations depend on exact age
- Legal: Voting age (18), driving age (18), drinking age (21/25 by state)
Leap Year Handling
Born on Feb 29? Your age calculator should handle this correctly. In non-leap years, Feb 29 birthdays are typically counted as Mar 1 for age purposes.
