I like The Photographer’s Ephemeris (https://www.photoephemeris.com/) which includes times for astronomical twilight, nautical twilight, civil twilight, as well as moon and sun rise and set times, golden hour, shadow estimation based on landmark position and height, and so many more great features. A very handy tool for location/photo scouting. Has a web app, APIs, and all the usual platform apps, too.
