You turn 13 on your birthday in 2012, and
you stay 13 until your birthday in 2013.
ask the person how old they are and subtract the age by the present year. exsample: how old r u? 10. I'll do the math: 2009 subtract 10 equalls 1999. You where born in 1999
If you were born in 1999 then you will be 12 in the year 2011
2016 − 1999 = 17 years old.
2061 - 1999 = 62
2016- 1999 _______ 17
13 years old he was born in 1999
The person who was born in 1999 would be 18 years old in 2017
If you were 22 years old you would be born in 1999
