Countdown til Sunrise/Sunset

Watchface Design Expression Help

Hi,

I’m wondering if anyone can help me with a countdown in hours and minutes until Sunrise/Sunset, IE a text display with; Sunset in X hours X minutes and then another one with Sunrise in X hours X minutes, I’ve already worked out how to make them transparent using $#DISDAYTIME#=true?100:0$ for each text display bit, just not sure how to add the countdown.

Hope this makes sence.
Thanks in advance :smile:

For how many hours are left:

(((#WRH#-#DH#)+24)-((floor(((#WRH#-#DH#)+24)/24))*24))

For how many minutes are left:

(((#WRm#-#Dm#)+60)-((floor(((#WRm#-#Dm#)+60)/60))*60))

#WRH# is for sunrise hour (0-23)
#WRm# is for sunrise minute
Change them for sunset tags to get the second set of numbers.

Question what the the “floor” element?

Floor basically rounds down to the lowest integer. So if you had floor(2.9), it would equal 2.

I found there was a issue with this equation. It had to do with the hour variables being constant till the next hour.
example or problem:
Sunset is 18:34
Time is 17:35
Return of equation 1h59M
We need 0h59m

I scratched my head for a long time and solved this small issued, based on the work merllin did, but converting everything to minutes in the hour equation so we could get a hour with decimal. Then we floor the number.

Here is what I have.

Sunset
(floor((((#WSH#*60)+#WSm#)-((#DH#*60)+#Dm#))/60))h
(((#WSm#-#Dm#)+60)-((floor(((#WSm#-#Dm#)+60)/60))*60))m

Sunrise: (day of)
(floor((((#WRH#*60)+#WRm#)-((#DH#*60)+#Dm#))/60))h
(((#WRm#-#Dm#)+60)-((floor(((#WRm#-#Dm#)+60)/60))*60))m

Sunrise day before:
(floor(((((#WRH#*60)+#WRm#)+1440)-((#DH#*60)+#Dm#))/60))h
(((#WRm#-#Dm#)+60)-((floor(((#WRm#-#Dm#)+60)/60))*60))m
