How Age Calculator Works
Our age calculator calculates your exact age in years, months, and days from your birth date to today. It accounts for leap years, varying month lengths, and provides accurate age calculations for any date range.
The calculation process:
- Calculates the difference in years between birth date and current date
- Adjusts for months, accounting for whether the current month has passed
- Calculates remaining days, handling month-end boundaries correctly
- Provides total days lived for precise age tracking
Example:
Let's calculate the age for someone born on January 15, 1990, as of December 20, 2024.
Given: Birth Date = January 15, 1990, Current Date = December 20, 2024
Step 1: Calculate Years
Years = 2024 - 1990 = 34 years
Step 2: Calculate Months
Since December (12) > January (1), the birthday has passed this year
Months = 12 - 1 = 11 months (from January to December)
Step 3: Calculate Days
Days = 20 - 15 = 5 days
Step 4: Calculate Total Days
Total Days = (34 × 365) + (11 × 30) + 5 + leap years
Total Days ≈ 12,410 + 330 + 5 + 8 = 12,753 days
Result: The person is 34 years, 11 months, and 5 days old, having lived approximately 12,753 days.
