Suppose you were born on March 5, 1990 and today's date is August 19, 2025.

Why Use an Age Calculator?

People use age calculators for many reasons, such as:

  • Birthday Planning – Want to know how old you'll be at your next birthday?
  • Official Documents – Some applications, forms or government requirements ask for age in exact years and months.
  • Health & Fitness Tracking – Doctors, dieticians and trainers often require age for accurate reports.
  • Genealogy & Research – Historians and researchers use age calculators to track events across generations.
  • Personal Curiosity – Ever wondered exactly how many days or weeks you've been alive? Now you can know.

Calculate Age Manually (Optional Guide)

If you ever need to calculate age manually, here's a simple method:

  1. Subtract your birth year from the current year.
  2. If your birthday hasn't happened yet this year, subtract one.
  3. Count the full months and days from your last birthday to today.

Example:

Born on March 5, 1990. Today is August 19, 2025.

  • 2025 - 1990 = 35 years
  • Birthday already passed this year → 35 years confirmed
  • From March 5 to August 5 = 5 months
  • From August 5 to August 19 = 14 days
  • Age = 35 years, 5 months, 14 days.

This matches the calculator output.
