Request: Add sunrise / sunset calculation? #79

Closed MacSass closed 4 years ago

MacSass commented 4 years ago

Hello, I really like this library - it works great, and still compact.

I´m not sure if this is totally out of scope, but was wondering if you could consider to add calculation of sunrise / sunset for a given place in local time ...

Best regards and thanks for the nice library - MacSass

Glad you like it!

Hmmm, that sounds more like a library of its own: all it needs is time, the rest is more geo-coordinate calculations. Or it might be part of some existing geo-coordinate library already. But there's also services online (some even free) that will give that to you for any given city, usually in combination with a crude weather forecast.

I'll close this here, but keep it in mind just in case.

I agree that sunrise/sunset it out os scope. Too many variables. https://www.timeanddate.com/astronomy/different-types-twilight.html

Ok, I do agree - was not sure myself, although I was looking for sunrise / sunset (when sun crosses horizon) not twilights - guess I was just selfish as I found ezTime a great working lib :-) ...
