January and February both date from about the time of Rome's founding. They were added to a calendar that had been divided into ten month-like periods whose lengths varied from 20 to 35 or more days. A winter season was not included, so those period lengths are believed to have been intended to reflect growth stages of crops and cattle.
When introduced, January was given 29 days and put at the beginning of the calendar year. February was given 23 days and put at the end. Then, for an undetermined period shortly after Rome's founding, months were said to have begun when a new moon was first sighted. At some later time, month lengths were separated from lunations and again became fixed. At that time, February's original length was extended by five days which gave it a total of 28.

I don't know why February has 28 days but on leap year there are 29 days because every 4 years(I think) the Earth rotates the sun for one more day than usual.

Even though we all learned that the earth revolves around the sun once a year, it's actually a few hours off. So every four years, adding a day keeps everything in balance. Since February has 28 days, it makes sense to add a day to this month.

it really is definitely due 5-10 days formerly the date on the bill in case you want a chit. when it comes to being due with assistance from the twenty 9th and there is not any date in that month, it really is due the twenty eighth. Pay early and avoid the hassles and pastime prices.
