Why does February have 28 days?

February (as well as January) first appeared on a schedule in regarding 713BC when Numa Pompilius (King of Roma from 715-673BC) added those two months to the existing 10-month long Roman schedule. He did so to make sure that the calendar accorded with the 12 lunar cycles (one lunar month is the time between 2 full moons thirty day (assembled)). A superstitious Roman, Numa intended to stay clear of months being of even number. So, he subtracted a day from each of the 10 30-day months to make them each 29-days long. However, due to the fact that he just had many days to play with given that the schedule accords with the lunar cycle, at the very least 1 month of the year had to be comprised by an even number of days. He chose February. Since it was last to be added, it was also the last month of the year till regarding 450 BC when it was changed to the second month on the schedule.

The schedule was substantially reformed in 46 BC by Julius Caeser. Caesers reforms brought the schedule in line with rotation of the sun (in contrast to the moon) which indicated that 1 year would amount to 365 days. In assigning the extra days, Caeser kept February with 28 days with the exception of in the jump year which occurs every fourth year in a four-year cycle. The Julian schedule continued to be the primary schedule used around the world for regarding 1,600 years. The Julian schedule is very acquainted to the solar dating system most generally used all over the world currently, the Georgian calendar. The Julian schedule operated a cycle of 3 normal years (365 days) adhered to by 1 leap year (366 days) and is based on one solar year lasting for 365.25 days. Nevertheless, this was an incorrect estimation. The right solar year worth is 365.24219 days (365 days, 5 hrs, 48 minutes, 46 seconds). The mistake indicated that on the Julian schedule, 1 extra day was acquired every 128 years!

The Gregorian calendar was announced by Pope Gregory XIII in 1582 to basically conquer this error. Although, its fostering was not immediate. Turkey was the last country to officially switch to the Gregorian calendar on 1 January 1927 (although it had actually changed for monetary functions in 1917)! Due to the fact that the error the Georgian schedule was introduced to overcome was not so large regarding accommodate an additional day being included right into the calendar, February was stuck with only 28 days (however, for leap years).
