March Listeni/mɑːrtʃ/ is the third month of the year in both the Julian and Gregorian calendars. It is one of seven months that are 31 days long. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20th or 21st marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March.
