why february is only 28 or 29 days?

Answer 1

The Earth circles the sun every 365 and 1/4 days. Every four years, to make up the extra day gained, we have leap year.
Why does February have only 28 days? You’d think with seven 31-day months, it would have been easy enough to give February 30, but calendars have never been easy. When the Romans first began working on the one that has become ours, February didn’t even exist.

The problem from the beginning was to reconcile the moon’s 29 1/2 day month with the sun’s 365 1/4 day year. The Romans’ first effort, supposedly devised by their founder, Romulus, included 10 months that added up to only 304 days. Clearly, Romulus had not conceptualized the problem.

The legend continues that King Numa Pompilius added January and February. The days now added up to 355, approximately the number in 12 lunar cycles but still 10 to 11 days short of a solar year. So Numa invented an extra month called Mercedinus that would be added to February every other year.

Numa’s calendar was getting closer to a system that would work, but its lingering attachment to the lunar cycle made it unwieldy. Julius Caesar decided to ignore the lunar cycle and get rid of Mercedinus by arranging the number of days in the twelve months to add up to exactly 365 1/4. February wound up with 29 days plus an extra every fourth year.

Julius Caesar’s calendar, which is referred to as the Julian calendar, is essentially the one we use today — with a few minor adjustments. It may have been Augustus, or maybe his admirers, who made the final adjustment to February. February 29 got shifted to August, which had been named in honor of Augustus, because August needed an extra day to be equal to July, which had been named in honor of Julius.

So that’s how February came to be only 28 days.

Answer 2

Greetings Bin Ladin!!! Does february 28 or 29 have some thing to do with 9 11? immediately is bounce 3 hundred and sixty 5 days so february has 29 days, 3 years to bypass which has 28 days in the previous yet another bounce 3 hundred and sixty 5 days

Answer 3

that's the way they set it up. it makes no real sense to me. they could make January, February and March 30 days each. the 29 is for leap year to make up for the extra 6 or so hours it takes the earth to go around the sun each year. otherwise the seasons would get screwed up and after like 100 years the seasons would be off by a month.

Answer 4

A widely believed--but possibly erroneous--story is that February is so short because the Romans borrowed a day from it to add to August. August was originally a 30-day month called Sextilis, but it was renamed to honor the emperor Augustus Caesar, just as July had earlier been renamed to honor Julius Caesar. Naturally, it wouldn't do to have Gus's month be shorter than Julius's, hence the switch.
This coule be the one of the reasons.
