What is an Age Calculator?
An age calculator is a tool that computes the exact time elapsed between a birth date and a specified end date (usually today). It provides precise results in years, months, days, and sometimes even hours and minutes.
This is particularly useful for determining eligibility for school admissions, retirement planning, birthday calculations, and verifying age requirements for various activities.
How Does Age Calculation Work?
Age calculation follows these logical steps:
- Years: Subtract birth year from current year
- Months: Subtract birth month from current month, adjust if negative
- Days: Subtract birth day from current day, adjust if negative
- Adjustments: Account for varying month lengths and leap years
Our calculator handles all these complex calculations automatically, giving you accurate results instantly.
