Question 133964
This could easily be a trick question.

How many birthdays do any of have? Answer 1. The rest are just celebrations of the anniversary.

However, what I think they want you to find out is how many leap years there are since 1944.

A leap year happens every year that is divisible by 4 EXCEPT years which are evenly divisible by 100 unless they are also evenly divisible by 400, in which case they are leap years.[

So, 2008 - 1944 = 64. years.
Every fourth year is a leap year, so 64/4 = 16
Since 2000 is divisible by 400, it is a leap year. So, your teacher is "16-1" or 15 years old

I would go with 1 :-D
