Red days

If you Google Calendario Escolar Almería 2023-2024 you’ll find (by scrolling down) a downloadable .pdf calendar. You can print it out if you wish.

Otherwise:

1) Google Spanish Bank Holidays you’ll get several sites.

2) View supermarket or shop websites such as https://info.mercadona.es/en/supermercados for horarios. This can also save you a trip to a town where they have special saint’s days etc. (we call them St Cantbearsed days) Albox is one such town.

Supermarkets in the villages generally open in the mornings on red days.

They all have websites, with opening times.

The larger supermarkets that are out of time done.
