Why does February have only 28 days? Why does it have 29 in a leap year?

Question

Thanks for the answers but it begs another...If one full rotation of the sun is 365.25 days wouldn't adding a day to the fourth year make it 366.25 days??

Answer 1

The extra day is to keep the Gregorian calendar as accurate as possible.

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by four, except for centennial years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not.

The reasoning behind this rule is as follows:

The Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox.[1]
The vernal equinox year is currently about 365.242375 days long.
The Gregorian leap year rule gives an average year length of 365.2425 days.
This difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years, the length of the vernal equinox year will have changed by an amount which can not be accurately predicted (see below). Therefore, the current Gregorian calendar suffices for practical purposes.

Answer 2

unquestionably it particularly is a political answer. The months that have been named for kings (Julius, Augustus) or gods (Mars, Janus) or had a god's birthday (December for Mithra, could for Jove) have been given greater effective days because of the fact they have been considered greater considerable months. There are in basic terms this sort of excellent variety of days in a year. February replaced into the month of options and atonement in Rome. Shortening the month of fasting replaced into good politics additionally. So while all the greater effective days have been long gone, the Romans began to take them from February. while it replaced into got here across that one greater day replaced into attainable each and every 4 years, Pope Gregory caught it into little short February.

Answer 3

February has 29 days in a leap year to make up for the extra 1/4 of a day we have every year. That's why leap year is every four years, and we have to add an extra day. If we didn't do this, we would have to add an extra six hours to each year. I hope that answered your question!

Answer 4

i dont know why it has 28 days but it has 29 because 1 full rotation around the sun takes 365 1/4 days so every four years we have to add more time on to make it true. But 28 days is weird. just make August shorter and February longer. idk!!

Answer 5

Julius and Augustus each stole a day for July and August. The extra day in leap years is to compensate for the fact that the year is actually 365 and 1/4 days long. Every four years we have to add a day or the seasons get thrown off.

Answer 6

Seriously, I have not a clue.
