How to Identify Birthdays Using MySQL Timestamps?

Determining Birthdays using MySQL Timestamps

To identify users celebrating their birthdays on any given day using MySQL timestamps, you can leverage the following query:

SELECT * 
FROM USERS
WHERE 
   DATE_FORMAT(FROM_UNIXTIME(birthDate),'%m-%d') = DATE_FORMAT(NOW(),'%m-%d')

Explanation:

• DATE_FORMAT: This function converts the UNIX timestamp stored in the birthDate column into a human-readable date string using the specified format.
• FROM_UNIXTIME: Converts the timestamp into a standard date and time format.
• '%m-%d': Specifies the date format as "Month-Day", which matches the format used in NOW() for comparison.
• NOW(): Returns the current date and time.

By comparing the formatted birthDate with today's date using DATE_FORMAT, the query retrieves all rows where the user's birthday matches the current day, making it possible to identify birthdays and send emails accordingly.
