How to Calculate your age by formula

To calculate a person’s age, you need to know their birthdate and the current date. Once you have both of these, you can subtract the birthdate from the current date to find the number of years, months, and days between the two dates.

The basic formula for calculating age in years is:

Age = Current Year - Year of Birth

For example, if someone was born in 1995 and the current year is 2022 then age would be 2022-1995 = 27.

To calculate age in months or days you’ll need to consider the birth month and birth day as well. You can use the current date with Date object and then use the getFullYear() method for year and getMonth() for months and getDate() for days in order to find the current year, month and day. Then use the same methods with birthdate to find the birth year, month and day. Then you can subtract the current date from birth date to get the exact number of months or days.

Please note that this only gives an approximate age, as it doesn’t take into account leap years or the exact date that someone was born. To get a more accurate age, you’ll need to also consider the month and day of birth. Also keep in mind that there are many other ways to calculate an age, this is a common and basic approach but may not be suitable for certain scenarios.
