How to Calculate Your Exact Age

While calculating your age in years is simple subtraction (Current Year - Birth Year), calculating the exact number of months and days is surprisingly tricky. You have to account for leap years (February 29th) and the fact that months have different lengths (28, 30, or 31 days).

Why Precision Matters

You might wonder, "Why do I need to know my age in days?" Here are the most common use cases:

• Government Exams: Many official forms require your age as of a specific cut-off date (e.g., "Age as of Jan 1st").
• Medical Records: Pediatricians often track a child's growth in months (e.g., "18 months old") rather than years.
• Retirement Planning: Calculating the exact time left until you are eligible for pension benefits.

The Math Behind the Calculation

If you were to do this manually, here is the logic you would follow:

1. Subtract the birth day from the current day. If the birth day is larger, borrow days from the previous month.
2. Subtract the birth month from the current month. If the birth month is larger, borrow a year from the current year.
3. Subtract the birth year from the adjusted current year.
