With the Presidential elections about a year off, I am going from time to time ask some Presidential trivia questions.

The first one is:

What Presidents were NOT elected on a leap year?

G Bush Jr, in 2000.

G Bush Jr, in 2000.

??? 2000 was a leap year ???

I'm gonna say Theodore Roosevelt.

2000 was a leap year and Teddy Roosvelt was elected to office as president in 1904 which was also a leap year.

2000 was not a leap year. If a year is divisable by four then it usually becomes a leap year BUT however if a year is divisible by four hundred then it is not a leap year. Maybe an extra day of thought would have done us some good that year.

2000 was a leap year. Just look at a calendar from that year. There is a February 29th. You are on the right track though. We use the Gregorian calendar. The Julian calendar had a leap year every four years.

The Leap 128 based calendar system is a hypothetical (http://en.wikipedia.org/wiki/Hypothetical) calendar system (http://en.wikipedia.org/wiki/Calendar_system) in which leap years (http://en.wikipedia.org/wiki/Leap_year) would be based on powers of 4 rather than the leap year every 4 years, no leap years every 100 and a leap year every 400 year system.

That being the case, then there can only be 2 possibilities

1800, Thomas Jefferson

1900, William McKinley

Riverwind is right about William McKinley. 1900 was not a leap year, but wrong about Thomas Jefferson. 1800 was a leap year. The other president was George Washington who was elected to the office in 1789 the year the constitution was raified by the states.

According to Wikipaedia:

Leap year rules

In order to get a closer approximation, it was decided to have a leap day 97 years out of 400 rather than once every four years. This would be implemented by making a leap year every year divisible by 4 unless that year is divisible by 100. If it is divisible by 100 it would only be a leap year if that year was also divisible by 400.[2][3] So, in the last millennium, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. In this millennium, 2100, 2200, 2300, 2500, 2600, 2700, 2900 and 3000 will not be leap years, but 2400 and 2800 will be. The years that are divisible by 100 but not 400 are known as "exceptional common years". By this rule, the average number of days per year will be 365 + 1/4 - 1/100 + 1/400 = 365.2425.

So both 1900 and 1800 were not leap years. Thus Jefferson and McKinley would be right.
