Question

In the year 2004, there were 5 Sundays in February. What are the last two digits of the next year in which this will occur?

Answer 1

The last two digits of the next year in which
this will occur is 32.

Answer 2

ok, so it has to be on a leap year, because only on leap years can you have february have anything with 5 days.
That makes it a lot easer.

365*3 +366 = 5 (mod 7) .... <>0 (or it would be sunday every leap year).

=>

2004 + 7*4 = 2032

Answer 3

in the year 2023
