As far as I know, the protestant Cantons (ZH, AG, BS, BL etc.) have Good Friday as a public holiday
as well as Easter Monday. The Tessin (catholic) is open tomorrow, but is closed on Monday. Probably most of the other catholic Cantons (LU, AI, SG) will be open tomorrow too.
You can check on the public holidays in your Canton here:
