The opening hours of the post offices vary very much from town to town and from borough to borough. The general opening hours are: Mondays to Fridays 10 a.m. to 5/6 p.m. In some instances, the post offices are closed on Saturdays. If the post office is open, it will be from 10 a.m. to noon or 2 p.m. Several post offices are situated in the same building as for instance super markets or shops, but they will always have the official post office sign posted  at the front of the building.
