Age Calculator Formula & Calculation

Age = (Current date − Date of birth) in completed years, months, and days

Accounts for leap years using 365.25 average days/year for total day counts.

Example: Born 15 March 1990, Today 19 June 2026.
Age = 36 years, 3 months, 4 days. Days lived = 13,244 days. Next birthday (15 Mar 2027) = 269 days away.
Day of birth = Friday. Generation = Millennial (born 1981–1996).

Key Factors That Affect Your Result

  1. Legal age milestones in India — 18: right to vote, get a driving licence (two-wheeler), sign contracts. 21: drinking age (in states with legal alcohol). 60: senior citizen IT benefits (higher exemption limit ₹3L). 80: super senior citizen (₹5L exemption limit, no advance tax).
  2. Leap year handling — A person born on 29 February celebrates their birthday on 28 February or 1 March in non-leap years depending on jurisdiction. Indian law typically counts 28 Feb for age purposes.
  3. Retirement corpus impact — At 25 with 35 years to invest at 12%: ₹10,000/month SIP builds ₹3.5 crore. Starting at 35 with 25 years: only ₹1.08 crore — one decade costs ₹2.4 crore. This calculator makes that visible.
  4. Health screening by age — ICMR guidelines: blood sugar screening from age 25 (earlier with family history), cholesterol from 30, colonoscopy from 45, mammography from 40 for women. Knowing your exact age helps schedule preventive care.
