Questions & Answers about El museo abre todos los días salvo el lunes.
Abre is the present tense of abrir and is very commonly used for opening hours, timetables, and routines.
- El museo abre... = the museum opens / is open
- El museo está abierto... = the museum is open
In practice, both can work in this kind of context, but they are not identical:
- abre focuses on the museum’s schedule or opening pattern
- está abierto focuses on its state of being open
So a notice about regular opening days often sounds very natural with abre.
Literally, abre means opens, but in sentences about business hours or public schedules, Spanish often uses abrir where English may prefer is open.
So in this sentence, abre todos los días is naturally understood as:
- it opens every day
- or more idiomatically in English, it is open every day
This is very common with shops, museums, banks, offices, etc.
