May is the fifth month in the Gregorian calendar and has 31 days. It is the last month of astronomical spring in the Northern Hemisphere and of astronomical fall in the Southern Hemisphere.
What Is the Meaning of May?
May comes from the Latin Maius, probably referring to the goddess Maia. She embodied the concept of growth, both in nature and in business. Others connect Maius with Maiores, the ancestors or “the greater ones.”
In May, the ancient Romans celebrated Floralia, a festival for fertility. Floralia lasted from April 27 to May 3 and included theater plays, dancing, and banquets. The Romans sacrificed a pregnant sow to the earth goddess Terra for a fruitful harvest.
Important Dates in May
May Day
Since ancient times, the beginning of May has been celebrated as the coming of summer—from the Roman Floralia to the Walpurgisnacht (Night of St Walpurga), a Germanic celebration with bonfires on April 30 still celebrated today.
Many countries in Europe and North America celebrate May Day on May 1 with dances around a maypole, a high wooden pole adorned with colors and flowers.
In many villages in Austria, a maypole is erected on April 30 or May 1.

Labor Day
In many countries, May Day and Labor Day are both celebrated on May 1. Labor Day started as International Workers’ Day. It goes back to labor unions fighting for an eight-hour working day. After a bloody demonstration known as the Haymarket Riot on May 4, 1886, Chicago’s workers’ union started their yearly protests on May 1, 1889.
May the 4th
May 4 is Star Wars Day because the date, stated as “May the fourth” sounds like the well-known phrase from Star Wars, “May the force be with you.” The sentence first appears in Star Wars: Episode IV – A New Hope (1977). The characters say it to wish each other good luck.
Two years after the movie was released, the Conservative Party in the United Kingdom congratulated their candidate, Margaret Thatcher, for being elected Prime Minister. On May 4, 1979, they published an ad in a newspaper saying, “May The Fourth Be With You, Maggie. Congratulations.” This might have been the beginning of May 4 as Star Wars Day.
Cinco the Mayo
Cinco de Mayo means “the fifth of May” in Spanish. The day is observed in Mexico and in parts of the United States on May 5 and celebrates the defeat of the French army during the Batalla de Puebla (Battle of Puebla) in Mexico on May 5, 1862.
In the US, Cinco de Mayo is seen as a day to celebrate the culture, achievements, and experiences of people with a Mexican background. Businesses promote Mexican food, drinks, and music, and traditional symbols of Mexican life are celebrated.

History of May
In the old Roman calendar, May was called mens maius and was the third month because the year started in March. In the year 154 BCE, a rebellion forced the Roman senate to change the beginning of the civil year from March to January 1. With this reform, May officially became the fifth month in the year 153 BCE.
This Roman wall calendar dating from 84-55 BCE shows “MAI” as the fifth month.
