Can the switch depend on e.g. Civil Twilight as well?

Describe the enhancement or feature you'd like

The from sunrise/sunset (location/coordinates) times don't match when there's actually enough ambient light outside. The sun illuminates the sky significantly before astronomical sunrise and after sunset.

Add an option to use e.g. civil twilight times (sun at -6° below horizon) instead of astronomical sunrise/sunset (sun at 0°).

Civil twilight represents when there's enough natural light for outdoor activities without artificial lighting, making it a more accurate trigger for theme switching.

• Civil twilight can start 30-60+ minutes before sunrise (varies by latitude and season)
• At high latitudes (like Nordic countries), the difference is even more pronounced

Describe alternatives you've considered

• Fixed time offsets don't work because twilight duration varies throughout the year

I like that

offering a bunch of different options probably makes sense like dusk, dawn, etc

The time governor already can dynamically calculate the time, so its probably not too much effort to extend the capacilities and then allow users to configure!

Fixed time offsets don't work because twilight duration varies throughout the year

They don't work for me either, so far I've just adjusted them twice a year 😄

Definitely a good feature idea!

You have any good hacks to propose? 😁

... tbh, I'd want to add / include an "ambient light" sensor 😅😝

If the day is cloudy - or anyway in a dark room, idk how much sense "switching" makes

OTOH, idk if anyone has solved that problem yet - so idk how to solve it (also my desktop has no ambient light sensor [and my desktop displays are not dimmable / configurable either]) - so idk what I would do, except trial and error 😅

We also have #193

You ppl are silly 😂🤣🤣😂

I love it (although, like the issue says, I don't see it getting much traction)

But it is always nice to have Windows hackers around 😁 (I know nothing of Windows development)
