May

May is the fifth month of the year in the Julian and Gregorian calendars and the third of seven months to have a length of 31 days. May is a month of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. Therefore, May in the Southern Hemisphere is the seasonal equivalent of November in the Northern Hemisphere and vice versa. Late May typically marks the  start  of the summer vacation season in the United States and Canada that ends on Labor Day, the first Monday of September. No month starts and ends on the same day of the week as May in any year. This month is the only month with these two properties. May however, starts and ends on the same day of the week as January of the following year. Also, in common years, May begins on the same day of the week as August of the previous year, and, in leap years, it begins on the same day as February, March, and November of the previous year.
