Unable to answer "What are the opening hours of Tillydrone Community Campus (Community Center)?" for https://osm.org/way/809710948 via StreetComplete 40.2:

Unsure of the actual Community Campus times. Hours for the library within the centre are Mo-Sa 10:00-13:00; Mo-Fri 14:00-17:00.

I will try and add the Library as a point within the centre soon, but if anyone knows the opening hours for the Community Campus itself, please add them.
