Why exact age matters
Many official processes require your exact age — not just birth year. Insurance premiums change on your birthday. Visa applications need age in years and months. Medical dosages can depend on exact age for children. Our calculator gives you years, months, and days.
Frequently asked questions
Start from date of birth to today. Count years first, then remaining months, then remaining days. For example: born 15 March 1990, today 8 June 2026 = 36 years, 2 months, 24 days.
Multiply years by 12 and add remaining months. Example: 36 years 2 months = (36 × 12) + 2 = 434 months.
Legally, most countries recognize March 1 as the birthday in non-leap years. Our calculator handles this automatically.
