do you know why that’s true?
Yes.
Normally it is considered that it takes 365 days for the earth to make a complete rotation around the sun. This isn’t true. It takes a little more. It takes approximately 365.2422 days.
If we would use a calendar with 365 days then we would end up with an error of 0.2422 days every year, which is almost six hours. After 100 years, the gap would have gotten so big that our calendar would be approximately 24 days ahead.
The leap years make the calendar more accurate. With our current calendar (the Gregorian calendar) the error is only about 27 seconds per year. 🙂
Didn’t we all learn that the year was 365 and 1/4 days, and the whole leap year thing in like 1st grade?
I know I did.
I would like to say Happy New year almost a month too late. 😀
sorry… im prolly not as smart as you… but ya i did know that the earth revolves around the sun every 365 1/4 days.. but it never really occured to me (nor had i really cared) that they had to compensate for the small deviation between the exact time it takes to revolve and 365.25
Am I the only one here who realises that its the 27th of January and people are still posting on the Happy New Year Topic?
