How Do I Calculate My Birthday Using My DO?

Birthday can be calculated by either of the following methods:

Method 1:

• Identify the current date
• Determine the exact month and day of your birthday
• If the current date and month have passed, add 1 year to the birth year
• If the current date and month have not passed, then the upcoming birthday will be in the same year

For example:

If your date of birth is April 20, 1999, and your current date is April 18, 2024:

• Current Date: April 18, 2024
• DOB: April 20, 1999

As April 20 has not passed, so the upcoming birthday will be on April 20, 2024.

Method 2:

• Enter your DOB in the birthday calculator and determine the next birthday and weekdays concerned with it.
