You can compute it: current_year - present_age = birth_year.
You were born in the year 1991 if you are 31 years old.
If you have already turned 31 in 2009 you were born in 1978, if you are 31 now and your 32 birthday is still to come this year, you would have been born in 1977.
This is 2010, right now. If you've already had your birthday this year, then you are 31 if you were born in 1979. If you have not yet had your birthday this year, and you were born in 1978, then you would be 31.
Well, honey, if you were 31 years old, you were born in 1990. Simple math, my dear, subtract 31 from the current year and there you have it. Now go on and enjoy being in your thirties, you spring chicken!
if you are 31 years old and its 2011 then you would be born in 1977
A person turning 31 in 2013 was born in 1982.
this year you are 31.... 1979 IS THE YEAR YOU WHERE BORN!!!!! so easy just follow this formula: step 1 year ____ age step 2 devide!!!!! :)
Calculated in 2010 the year of birth was 1979.
Given the current year of 2010, if you have already celebrated your birthday this year, you would have been born in 2010 - 31 = 1979. If you had not yet celebrated your birthday you would have been born in 1978.
