Saturday December 6 is the Day of the Constitution in Spain and is a national fiesta so expect most shops and services to be closed although bars and restaurant normally open.
Monday December 8 is the Day of the Immaculate Conception, a national, religious fiesta day and the same applies.
Many busineses make a «bridge» on these dates covering Saturday, Sunday and Monday but as Sunday is always a fiesta day in Spain the closures only apply to Saturday and Monday.
