Question

What will be the formula on how to solve the remaining days before the birthday of a person?

If Given are:

1.his/ her birthday
example:

birth day: 05

birth month: 07

birth year: 1996

2.current date

current day: 05

current month: 01

current year: 2012

and this is needed to be satisfied

1.BIRTH MONTH > CURRENT MONTH

2. (BIRTH YEAR r 400 = 0) <<< LEAP YEAR>>>

N(BIRTH YEAR r 100 = 0) <<< NOT A LEAP YEAR>>>

r = remainder

20 r 4 = 0
20 r 3 = 2
