When looking for another video to give a review on, I stumbled upon this one. I really wanted to learn about this because I was always confused on how leap days and leap years worked. I would see on different social media sites what day it would be if we didn't have any leap days or years. It was always something crazy, like it being July when in reality we were still in winter months. I always wondered how we figured that out, and why.
In this video, I learned that the amount of days that the Earth revolves around the sun is not easily divisible. There isn't an even amount. Neil said that it would take about 365.25 days. That being said, the small margin could become a very big problem if we ignore it.
This is why, every four years (.25 x 4), we have a full extra day in the year. He talks about how we take that day on the fourth year and give it to the neediest month. This would be February. Then he goes on to recount that it isn't perfectly 365.25 days, it's a little less. This means that every time we put in an extra day, we are over-compensating, and in return, every 100 years you need to take out the leap year that would have been there. But by taking out that extra day, it over-compensates in the other direction. This means that every 400 years, you need to put in the leap day. This all came to fruition in 1582, which I though was super interesting.
I was really interested in learning about this because I have a friend who was born on a leap day in 2000, which was a year that should not have had a leap day, but ended up having one because it was divisible by 400 years. So close.
Learning about this was really interesting and I actually found out a lot about this topic. It kind of reminded me of math, which was kind of weird, but I guess that math and science go hand in hand.
