![]() Again, I'm no expert or mathematician, but I'm sure someone more qualified can give an explanation as to why. So only one of the four end-of-century years in 400 years is a leap year. Will 2020 be a leap year 2020 is divisible 4 ( 505). So, we conclude that 2000 was a leap year. If a year is divisible by 100, but not 400, then it is not a leap year. 4 Check if the number is evenly divisible by 400 to confirm a leap year. That means that 2000 might not be a leap year and you will have to divide it 1 more time. 2000 is divisible by 100 (2000/100 20), So, it could not have been a leap year, but 2000 is divisible 400 ( 2000/400 5). 2000 is divisible by 4 and it is also evenly divisible by 100 since it leaves a result of 20. I believe the reasoning for this is because a year isn't actually exactly 365.25 days, it's more like 365.24255 days, so they need to compensate for the 42 minutes that are gained every leap year somehow. And year 2000 was a leap year, but 2100, 2200, and 2300 are not. Was 2000 a leap year 2000 is divisible 4 (2000/4 500). Which is why the year 2400 will still be a leap year, even if it's divisible by 100, because of the fact that it's divisible by 400. For example, 2100 will not be a leap year because 2100 is equally divisible over 100.The second condition is that the previous condition is overruled if the year is also divisible by 400. The first rule most of us know is that a leap year occurs every 4 years, which adds an extra day to the February calendar.However, this rule isn't applied to any year that's divisible by 100. The rules for when a leap year happens actually has 2 extra conditions that aren't often mentioned because they are almost never used. To figure out if a year (say, 1999) is a leap year, you need to test whether it is divisible evenly - that is, if there is no remainder after the division - by three different values.For anyone who is curious as to why there isn't a leap year on the year 2100 or 2200, 2300, 2500, there's an explanation. The fact that it is approximately 365.25 days should mean that leap year should come every fourth year.īut, things are a bit more complicated than that because one revolution around the sun is almost but not quite 365.25 years, so leap years come slightly less often than once every four years. The next time a leap year will be skipped is the year 2100. 2000is perfectly divisible by 400, So, it is a leap. Leap years let the calendar adjust for the fact that it takes the earth takes slightly over 365 days to revolve around the sun. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. Century years are leap years if they are divisible by 400. The original four-year rule was defined in 46 BC by Julius Caesar to adjust for the one-quarter day left over at the end of each year. By whom was the leap year invented Leap years were first introduced in the Western calendar. Some years in our (Gregorian) calendar are "leap years." In a leap year, February has a 29th day and the year overall has 366. This means that the year 2000 was a leap year, although 1900 was not.

In a CS10 class, students might be comfortable with the subjectivity of this question based on their classroom culture, but I would think most high school math or computer sceince students are going to be expecting questions to have a "right answer" and if we want to ask questions like this, we might need to be careful to help teachers build a culture that is more comfortable with questions like this. Q5 Among the following, which was not a leap year 2000 2004 2007 2012 Show Answer. MF: The last question here ("Which script is the most beatuiful?") is a tricky one.And there are a lot of different constraints with this leap year issue. Divisibility might not be a comfortable topic for our NYC students. MF: Again, I'm wanting us to be mindful of mathematical level here. ![]()
