Most supermarkets in Barcelona and across Catalonia will close on Wednesday, 1 May, for Workers' Day, according to Diari Catalunya. This closure will affect major distribution chains throughout the region.

While the majority of stores will be shut, some exceptions may apply. Holiday opening hours in Catalonia can vary depending on the type of public holiday and the specific town or city. This means certain stores, such as some Caprabo branches, might remain open with special schedules.

To avoid unnecessary journeys, shoppers are advised to check the specific opening hours for their local supermarket before travelling, officials said.
