How many Leap Years were there between 1890 and 1910 (inclusive)?

Normally, a year is a leap year if it is divisible by 4, but a year which ends "00" is only a leap year if it is divisible by 400. That's the difference between the Julian and Gregorian calendars, so 1900 wasn't a leap year, but 2000 was. The next "00" leap year isn't until 2400.

Dezzy Ray Dunn 364 1/4 overstates the real length of the year slightly. Take a look at http://www.timeanddate.com/date/leapyear.html. Seems the problem was, if not reformed, eventually Christmas and Easter would have collided.

Wr5ong. 1900 was not a leap year - follow the link http://www.timeanddate.com/date/leapyear.html

Suzy Ellen, according to the bonus quiz it depends on which calendar you are looking at, Julian and Gregorian... but the question didn't mention based on which calendar.

the question did not ask if it were Julian or Gregorian calendars, so 1900 is dividable 4

Suzy Ellen, read explanation.

Helga U. Williams

Oh well, I divided by four and chose 5 🤣

If 1892 was a leap year, supposedly it was then every 4 years from then is a leap year. 1896, 1900, 1904 amd 1908. I would love an explanation as to why the 1900 leap year was skipped. Cheers

I have a cousin with a leap year birthday

Satish Chandran, unless divisible by 100 but is if divisible by 400. so 1900 was not a leap year. 4 is the correct answer

ninakamwene, Usually, we would need a 24-year span to have six leap years, one every four years. I am glad the question taught you about leap years. Thank you, Christine, James' wife

1892,1896,1900,1904,1908,these years r divisible by 4. So 5 leap years between 1890-1910.

Elma Morgan, 2000 is divisible by 400 (as stated in the explanation)

Need an explanation for the year 2000 then. Was 2000 a leap year because it has three ooo's. Just want to understand the rationalizing of the four year rule then

Who came up with divisible by 400? And can I go back in time and query their logic?

Irene Townsend

Good question and info. Easy to work out

I was taught that if the last two digits of the year was divisible by four, it was a leap year. So where did those extra 1/4 days go? We better ask the Mayans or Incas.
