For a sun[rise/set] progression rather than flip I made a test face a while back:

You should remember it. This ring a bell on one of your faces? This was my work-through face helping with the expressions on that.

Thank you for that I was reading that one before and the info was great but was having problems with the face i have its not on the top but on the side was having problems with the numbers. Pulled all my hair out :slight_smile: I made it just switch from day to night instead of the rotation. Someday I will figure that part out.https://beta.facer.io/watchface/HFZrK36le8

I’ll see if I can add a rotary circle to the demo face. The expressions may well boggle me at first. It’s been a while. I wonder if it was before I started keeping regular files of all the complex ones with annotations.

Fantastic face though.

So you used two same images differently rotated and switched them with opacity like $#DISDAYTIME#=1?100:0$
You could do the same with just one image with 100 opacity, and rotation like $#DISDAYTIME#=1?0:180$
Question is, how do you imagine the rotation? That the image will continuously turn over 24h, or that it does some slow turning in the minutes (how many) around sunset/sunrise, or it just flips like I described earlier?

was thinking it would be a slow rotation based on time so the sun and moon will show at the same time at some point

Ok,
a) set the image opacity to 100 (no formula there)
b) set the rotation like this
(180+9*(clamp((((#WSUNRISEH#*60)+#WSUNRISEM#)-(#DH#*60+#Dm#+#Ds#/60)+10),0,20)+clamp((((#WSUNSETH24#*60)+#WSUNSETM#)-(#DH#*60+#Dm#+#Ds#/60)+10),0,20)))
it will start 10 min before and finishes 10 min after the sun goes up or down
c) cosmetics: I would change the cutout shape, or shift the rotating image more to right, to avoid the corners showing the opposite side
