Video Title :- How to create Age Calculator In JavaScript|Javascript Projects | College Project 2 - CodeWithRihan



About Video :- Creating an age calculator in JavaScript involves calculating the difference between the current date and a user's birthdate. Here's a brief guide:

1. Get the Current Date and Birthdate : Use JavaScript's `Date` object to retrieve the current date and create a new date object for the birthdate.

2. Calculate the Difference : Subtract the birthdate from the current date to get the difference in milliseconds, and then convert this into years.

3. Adjust for Date Differences : Handle cases where the birthdate hasn't occurred yet this year by adjusting the calculated age.


Explanation:

'today.getFullYear()` and `birth.getFullYear()` provide the current year and the birth year.
`today.getMonth()` and `birth.getMonth()` compare the current month with the birth month.
The `if` condition adjusts the age if the birthdate hasn't occurred yet this year.

This approach ensures that the age is accurate based on the birthdate provided.
