This is to keep our current calendar aligned with the solar year and astronomical seasons marked by equinoxes and solstices. The Gregorian calendar consists of the following 12 months:. The word month is even derived from the word Moon. As far as we know, months were first used in Mesopotamia sometime between the years BCE and BCE to measure the natural period related to the lunar month , or synodic month, which is the time it takes for the Moon to go through all the Moon phases.
The Gregorian calendar has 4 months that are 30 days long and 7 months that are 31 days long. 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.
