Sun/Moon widget without online GPS and internet connction

Is there any sun/moon widget, that doesent require constant gps lock and internet conection from cellphone? I like to have information about sunrise and sunset like on standard watchface, but now i want to use custom wathface which doesent have that information so i need widget for that.
I tried Weather and Sunrise/Sunset Widget and Garmin Sun & Moon, both require GPS and first one require internet from cellphone.
How is it possible to have sunset sunrise on garmin standard watchface without gps active?

To calculate that, you need to know where you are. Hence GPS and/or bluetooth/internet.

I understand that, but is there an app that uses only last known position without activation GPS for their own? Like garmin standard watch face?

BigWeather uses the last known position and shows sunrise and sunset.

From description i understand that BigWeather requires internet connection, but i will check it.

Correct. How do you expect a watch to get this kind of data without going out to get it?

I was thinking of caching the info so in the event there s no internet conenction it'll use the last data BUT that could be old/inaccurate if you had moved say 100 miles since the last connection.

Are you wanting an app to be able to know the sunrise/sunset without EVER connecting the GPS / Internet? If so, good luck!

The same way as standard watchface of garmin? It shows sunset and sunrise without GPS and internet connection active.
Not ever, only last know position.

I found one https://apps.garmin.com/pl-PL/apps/b0cf2bfe-7eba-436a-a309-4d59709b3f4d
Sunrise/Sunset Widget
Features:
-Accurate sunrise/sunset time calculation without active GPS or phone connection.

So it is possible. Its shame that there is no Epix version :(

i think you missed a point I'm the app you linked.
It uses the last known position but you also need to have a last known position and you can only get that when you at least enable GPS /Internet at least once.

That's what the app desc says.

In all these sunrise sunset things. There is a formula to calculate but it also uses the location to calculate it. Which again implies that You need to enable it once.

Ok, i am no programmer. I thought that last know position is stored when i use app like running or cycling with GPS, co widget can use that position without using GPS by itself.

its not about Yu being a programmer or not. I would term it as presuming too much as in what are the capabilities that garmin SDK exposes to developers.

In this case, I'm not sure if last known position is actually provided to end user apps or SDK.

in any case, even if you use run/hike etc apps where GPS is enabled, what's wrong with enabling the GPS for the app for it to get the current position? It's not like the GPS is asked to be turned on the entire time, just one-shot to g et the current position.

Then calculations can be done. Or.... The other alternative is connect to Internet and query some service with the lat/Lon to get the data.
