Calan Mai: What Is It?

Calan Mai, celebrated on May 1, is an annual May Day holiday of Wales. The day marks the arrival of warm season and also considered as one of the three ‘witches night’ – the other two being St John’s Eve and Halloween. It is said that the veil between this world and that of the next was opened, namely the OtherWorld, and dead spirits are free to roam abroad among the human beings on Earth.


The origins, and the customs and traditions associated with Calan Mai, directly match with those of May Day, Walpurgis Night, and Beltane Fire Festival – that is the celebration of spring and lighting of bonfires to ward off evil spirits and witches.

Calan Mai History: Why’s This Day Celebrated in Wales?

The historical background of Calan Mai is parallel to that of May Day, Beltane Fire Festival, and Walpurgis Night. Ancient people believed this day as the day when the boundaries between this world and the world of spirits are removed, and when all the evil things of Earth and air and water held revel. So a custom of lighting huge bonfires and making loud noises was developed in different regions since evil spirits hate fumes and loud noises.

Secondly, Calan Mai was the celebration of the coming spring as well as a time to begin a new cycle of agriculture and herding. The old farmers celebrated this day because they could start farming from now on. It was the time of animals waking up from hibernation. So some farmers would celebrate the day their cattle were going to the forest to start their summer pastures.

In ancient times, the first day of May was celebrated as a start to fresh spring, bid farewell to the harsh winter, and enjoy the arrival of warm weather. People would often engage in cultural dances, singing, and feasting activities to mark the revival of nature and enjoy the summer sunshine.

Calan Mai Festival is a combination of all these historical events and cultural practices. Today, Calan Mai is observed on May 1 in Wales and is celebrated in the same fashion as it has always been.

Calan Mai Customs & Traditions: How’s This Festival Celebrated in Wales?

On May Eve, villagers collected branches and flowers that they used to decorate their homes outside and to celebrate new growth and fertility. In Anglesey and Caernarfonshire, “playing straw man” or “hanging a straw man” would be a common practice on Calan Mai.

A man who lost his sweetheart to a man would make a man straw and put him somewhere near where the girl lived. The stray man depicted her new boyfriend and had a note pinned on her. The situation often led to a fight at the May Fair between the two young men.

Calan Mai would be the time for a funny fight between two seasons, the summer and winter. The man who represented Winter season carried a blackthorn stick and a shield that had wool on it to show snow. The man representing Summer season had a willow wall, with spring flowers tied with rubbers, adorned with garlands of flowers. A funny battle occurred in which Winter forces threw straws at the summer forces who repressed them with willow bunches and young ferns.

The Festival takes place on the May Day Bank Holiday and is a traditional springtime festival celebrated annually.

Finally, the Summer forces won and a May King and a May Queen were selected and elected to office, followed by feasts, dances, games, and drinks until the next morning. A feature of the May Day celebration was summer dancing and drinking. The singers went with a harpist or fiddler to visit the families on the morning of Calan Mai (May 1) and greeted them through the season. They would be rewarded by food, drink and possibly money if their singing and dancing were considered valuable.
