Calculate Your Age! →The Basic Age Calculation Formula
The most common method subtracts the date of birth from the current date. However, this only gives you the total number of days lived. To break this down into years, months, and days requires some adjustments.
The basic formula looks like this:
Age = Current Date - Date of Birth
This result is then typically converted to years, months, and days using more complex calculations to account for varying month lengths and leap years.
Breaking Down the Components
To understand the age calculation, consider these steps:
- Years: Subtract the birth year from the current year.
- Months: Subtract the birth month from the current month. If the current month is earlier than the birth month, subtract 1 from the year difference and add 12 to the month difference.
- Days: Subtract the birth day from the current day. If the current day is earlier than the birth day, subtract 1 from the month difference and add the number of days in the previous month to the day difference.
Cultural Variations in Age Calculation
It's important to note that age calculation can vary across cultures. In some Eastern cultures, a person is considered one year old at birth, and their age increases at the Lunar New Year, not necessarily on their birthday. However, our calculator uses the most common Western method.
