May Day is known as la Fête du Travail in France and celebrated with a public holiday. It is an occasion to be seen to campaign for workers’ rights and social justice but the date also carries a much older tradition here; it is also la Fête du Muguet, when sprigs of muguet or Lily of the Valley are presented to loved ones. It is also the day of one of the most important festivals celebrated by the ancient Celts, Beltain.
