@rmi@cloudisland.nz OTOH there are different times for civil, nautical, and astronomical, twilight and dawn / dusk. Because the definitions differ on how far from the horizon the sun needs to be for it to count. The differences are each about 6 degrees of rotation, which is a non-trivial amount of extra time (~24 minutes based on some quick maths). https://www.timeanddate.com/astronomy/different-types-twilight.html https://en.wikipedia.org/wiki/Twilight
