You can do this by:

Find your birth date (e.g., June 15, 2000).

Count your age by subtracting your birth year from the current year.

Example: 2025 - 2000 = 25 years old.

Use a calendar or tool to check what day of the week your birthday was.

To find the next birthday, check this year’s calendar to see if your birthday has passed or is coming.

Date of Birth: March 10, 1995
Today’s Date: July 14, 2025
