Age Calculator
To calculate someone's age, you must know their birthdate and their current date. Here is how you can calculate someone's age: Determine the person's birthdate you want to calculate.
Determine the current date. You can do this by looking at a calendar or using an online date calculator.
Subtract the birth year from the current year to find the years between the two dates. For example, if the person was born in 1990 and the current year is 2023, you would subtract 1990 from 2023 to get 33.
If the current date is before the person's birthday, subtract 1 from the result. For example, if the person's birthday is in October and the current date is in March, subtract 1 from the result.
If you want to know the person's age in months or days, multiply the number of years by 12 for months or by 365 for days.
Here is an example: If someone was born on March 12, 2000, and today's date is March 31, 2023, their age would be calculated as follows:Birthdate: March 12, 2000
Current date: March 31, 2023
Calculation: 2023 - 2000 = 23
Result: The person is 23 years old.
To calculate their age in months or days, multiply the result by the appropriate factor (12 for months, 365 for days). For example, 23 x 12 = 276 months or 23 x 365 = 8,395 days.
