How do you write your date of birth?

The international standard recommends writing the date as year, then month, then the day: YYYY-MM-DD.

How do you manually calculate age?

The method of calculating age involves the comparison of a person's date of birth with the date on which the age needs to be calculated. The date of birth is subtracted from the given date, which gives the age of the person. Age = Given date - Date of birth.

How do you calculate age in database?

We can find the age of a person from their date of birth by using this formula: SELECT DATE_FORMAT(FROM_DAYS(DATEDIFF(NOW(),'DATE_OF_BIRTH')), '%Y') + 0 AS age; In the above formula, we are first finding the difference between the current date (NOW()) and the date of birth (in YYYY-MM-DD) using the DATEDIFF() function.
