May Facts for Kids

2025 Calendar

May is the fifth month of the year in both the Julian and Gregorian calendars. It has 31 days.

In the Northern Hemisphere, May is a spring month. But in the Southern Hemisphere, it's an autumn month. This means May in the Southern Hemisphere feels like November in the Northern Hemisphere. In the United States and Canada, late May often marks the start of summer vacation, usually ending around Labour Day in September.

The name May comes from the Latin word Maius. It was named after Maia, a Greek goddess who was also linked to the Roman era goddess of fertility, Bona Dea. Her special festival was held in May. Another idea, from the Roman poet Ovid, is that May was named for the maiores, meaning "elders," while June was named for the iuniores, or "young people."
