In terms of efficiency, meaning to reduce the number of tests, I'd test the most probable one first, i.e. year % 4, which becomes 0 every fourth year, as opposed to year % 400, which becomes 0 every 400th year only (and not for the next 385 years., btw). So in the vast majority of cases, you'll be off with one single test only.
