How many april days

February is the only month that is 28 days long in a common year and 29 days long in a leap year. The Gregorian calendar has days in a common year , and days in a leap year.

The ancestor of our modern calendar, the ancient Roman calendar , had only days. Our current Gregorian calendar and its predecessor, the Julian calendar , both have 12 months.

The month names we use today are derived from the Roman calendar , which initially had only 10 months , with the calendar year starting in March Martius. The Romans named some of the months after their position in the calendar year: September means the 7th month, October the 8th, November the 9th, and December the 10th month. However, when January and February were eventually added and the beginning of the calendar year was moved to January, the position of these months no longer corresponded with the original meaning of their names.
