I heard somewhere that it's called the Golden birthday. It's supposed to be celebrated better than just an average birthday party!
I believe it is called your "Platinum Birthday". The "Golden Birthday" is when you turn the same age as your birth date (ex: 24 on the 24th).
It does not have any special or particular name.
Since age is done by the date only (individual times would be impossible to regulate) then you can do whatever you are allowed to do at that age, as soon as it is the date of your birthday - the date changes at midnight, so you are 21 as soon as the clock reaches that time.

In 2011, you're 20 until your birthday, and on your birthday, you turn 21.
Date of birth is Qualitative, but age is Quantitative.

Ah, your bronze birthday, how quaint. It's when you turn the age that matches the day and month you were born. So, if you were born on the 15th of May, your bronze birthday would be when you turn 15. It's a fun little coincidence, but let's be real, it's just another excuse to eat cake.
Subtract the current year minus 1949. Then, if the date in the current year is before the person's birthday (the person didn't celebrate his birthday yet), subtract 1 from the result.
Ah, what a delightful concept! When your age matches your birthday, it's called a "golden birthday." It's like a special little gift from the universe, a moment where your age and the date align perfectly. Just imagine the joy of celebrating such a harmonious occasion!
It is called your "Beddian" birthday! :)
Until your birthday in 2010, you would be 18. On your birthday in 2010, you would turn 19.
