Not quite. There is a more complex formula because an orbit around the sun is NOT exactly 365.25 days, it's 365.2422. Every once in a while you skip the leap year to account for the missing 0.0078 days (11.2 minutes).

The year is evenly divisible by 4; If the year can be evenly divided by 100, it is NOT a leap year, unless; The year is also evenly divisible by 400. Then it is a leap year.

1900 was NOT a leap year because it didn't meet the above formula, 1896 was, 1900 was not, and the "next" leap year was 1904.
