Thank you for your post.
The Gregorian Calendar says a leap year occurs every four years, except on the century, unless that century is divisible by 400. That is, 1700, 1800, 1900, 2100, 2200, 2300, 2500, ... are NOT leap years. 1600, 200, 2400 ARE leap years. Therefore, the information you receive is correct. 2000 was a leap year, and it should result in 366.
Thank you for the clarification. I thought I remembered 2000 being an exception, but as it turns out, it was the exception to the exception and I misread my internet research on the subject.
