If you were 21 you would be born in 1987.
If you are 21 in 2013, then you were born in 1992.
You would be born in 1969.
2011 - 21 = 1990
Born June 25 1990 would make you 21 today.
The calculation would be Current Year - 21 = Birth Year. To be 21 today, you have to be born on or before today's date of that year. Example: Today is June 27, 2007. 2007 - 21 = 1986. You are at least 21 years old today if you were born on or before June 27, 1986.
2001 would be the year of your 21st birthday.
2015 − 1994 = 21 Therefore, you would have been born in1994
Calculated in 2010, the year of birth is 1989.
You would be 21 years old on your birthday.

In the year 2014, if you had had your birthday you would be 21, if not you would be 20.
A random guess: I would say 1993 + 21 = 2014.
1996 + 21 = 2017
1992 (today = 16 March 2013).
2013-1992=21 So during this year you will have your 21st Birthday.
If you are 21 years old, you were born in 1990. (2011)
he is 21 so if u do the math, it would be 1990 that Charlie Scene was born in. ** If you would've done ur math RIGHt and he's 21 then he would've been born in 1989 not 1990**
20 years old as of 2010. You would be then turning 21 before the year of 2010 is over.
Take 21 from the current year if you have had your birthday, if you have yet to have your birthday in the current year take away 22
If someone turns 21 in 2011 then they were born in 1990. If someone's birthday is in January, February, March, April, May, June, July, or August 1990, then they would turn 21 in those months in 2011. The majority of their 21st year is in 2011. However, is someone's birthday is in the later months- September, October, November, or December- of 1990, then they would turn 21 in the last four months of 2011, and a major piece of their 21st year would be in 2012. Which means that as of October 2012, they would just be turning 22.
People turning 21 in 2018 were born in 1997.
