Probably the simplest way is to use the API at
https://sunrise-sunset.org/api .
Also, the OpenWeatherMap API will give you sunrise and sunset for a location along with weather information.
If you want to do this by purely mathematical means without web access then there is a discussion thread here :

(Hint - It's extremely complex.)
Cicciocb, I hope you don't mind a link to an alternative microcontroller forum. Please delete if you do.
Picaxe has it's uses but ESP8266 / ESP32 has WIFI

Panno, this was already covered in the old forum:

As AndyGadget says, I think the system that pointed
fu-ma ... @ berlin.de is the most suitable.
And the one suggested by Electroguard, the simplest.
I provide you with a simple code that can help you. You must take into account that you have to add the hours of difference of your place, in my case two.
Code: [Local Link Removed for Guests]
' In memory of M.R. James
lat$ = "43.0275"
lng$ = "0.570833"
r$ = wget$("api.sunrise-sunset.org/json?lat="+lat$+"&lng="+lng$, 80)
' wlog r$
sunrise$ = json$(r$,"sunrise")
sunset$ = json$(r$,"sunset")
wlog "sunrise at "; sunrise$
wlog "sunset at "; sunset$
This only returns data for the current day, but you will see that it is easy to interrogate the API with future days on the original site:
