I am a sundial. I'm prepared to bet
Your watch can't tell when the sun will set
I once heard Frank King talk about sundials in particular this very cool one, which measures Babylonian hours (hours since sunrise) and Italian hours (hours since sunset)
I am moving house and thinking about making my own, but none of the walls face exactly South. One of the walls faces approximately South-southeast (haven't measured exactly yet).
Would it still be possible to make a sundial like that? I understand it would be shaded for the last couple hours of the day (when the sun is in the west)
