How It Works
How to Calculate Exact Age — Formula, Leap Years & Common Mistakes
Calculating your exact age in years, months, and days is trickier than it looks — months have different lengths, leap years add a day, and most simple methods get it slightly wrong.
Step-by-Step Age Calculation
Exact Age (Years → Months → Days)
Age = (Today − Date of Birth)
Step 1: Subtract birth year from current year
Step 2: If birthday hasn't occurred this year yet — subtract 1 year, add 12 months
Step 3: Subtract birth month from current month for remaining months
Step 4: If birth day > today's day — borrow a month and adjust days
Example: Born November 15, 1990 — Age on July 2, 2026
1
Years: 2026 − 1990 = 36, but the November birthday has not passed yet → 35 years (last birthday: 15 Nov 2025)
2
Months: from 15 Nov 2025 to 15 Jun 2026 = 7 months
3
Days: from 15 Jun to 2 Jul = 15 days left in June + 2 = 17 days
✓ Age = 35 years, 7 months, 17 days
Why Most Quick Calculations Are Wrong
- Simple subtraction (years only) — ignores whether your birthday has passed yet this year.
- Dividing by 365 — ignores leap years (off by ~6 days per decade).
- Multiplying by 30 for months — months have 28–31 days.
Leap Year Birthdays
Born on February 29? This calculator correctly handles leap day birthdays (uses March 1 in non-leap years).
Age in Days, Hours & Minutes
