How your golden birthday is found
Take the day of the month you were born. That number is your golden birthday age. Add it to your birth year to get the year, and the date is your birthday in that year.
Everyone has exactly one golden birthday. If yours is still ahead, you can start a birthday countdown to it. For your current age, use the Age Calculator, and for a second celebration every year, see your half birthday.
Worked example
Born March 21, 1996. The day of the month is 21, so the golden birthday is the 21st birthday: 1996 plus 21 is 2017, which makes it Tuesday, March 21, 2017.
How to find your golden birthday by hand

- That number is the age of your golden birthday.
- Add it to your birth year: 1996 plus 21 is 2017.
