May

May is the fifth month of the year in the Julian and Gregorian Calendars and one of seven months with the length of 31 days.

May is a month of autumn in the Southern Hemisphere and spring in the Northern Hemisphere. Therefore May in the Southern Hemisphere is the seasonal equivalent of November in the Northern Hemisphere and vice versa.

No other month begins or ends on the same day of the week as May in any year. January of the following year always begins and ends on the same day of the week as May of the current year.
The month May was named for the Greek goddess Maia, who was identified with the Roman era goddess of fertility, Bona Dea, whose festival was held in May. Conversely, the Roman poet Ovid provides a second etymology, in which he says that the month of May is named for the maiores, Latin for "elders," and that the following month (June) is named for the iuniores, or "young people" (Fasti VI.88).
In Slovene, the most established traditional name of May is veliki traven, meaning the when plants grow. It was first written in 1466 in the Škofja Loka manuscript. There are numerous other names for it, for example majnik, cvetnar, rožni mesec. The latter two relate to flowers blossoming.
