Calculate Age Mannually
You cannot calculate date of birth from age only, if age is expressed as a positive integer. However to calculate age as years, months, days First Calculate the Years. 2011 minus 1988 = 23 years Next Calculate the months August =8 Next you need month of your birth Since it is August also 8 and 8-8 = 0 I'm going to note that if you were born in April you would do 8 - 4 = 4 months If you were born in December, you would get 8 - 12 = -4 . That is negative because you have not had your birthday yet so we would borrow 12 months, subtracting 1 year and take you down to 22 years {which you were before your birthday and then -4+ 12 would be 8. That would have made you 22 years 8 months. As it is, you are 23 years 0 months. Next Calculate the days. Since this is day 27 of August you would find 27 - 14 = 13 days so your age is ******************************...
