May 1st is a mandatory public holiday in Greece, and most businesses, including the majority of supermarkets, are required by ministerial decree to remain closed. However, some larger supermarket chains may operate with reduced hours, while smaller convenience stores and mini-markets are more likely to stay open, particularly in tourist areas. If you are visiting Crete around May 1st, plan ahead by stocking up on groceries and essentials the day before. Bakeries, kiosks, and some tourist-oriented shops typically remain open. Restaurants and tavernas generally operate as usual. Petrol stations follow a rotation system, so at least some will be available. The holiday also coincides with traditional flower-gathering celebrations and local festivals across the island, making it a lively day to explore village squares and coastal promenades.
