Part 107 lets you fly day and night β but the rules change with the light. Get today's exact daylight, civil-twilight, and night windows for your location, and see when you can fly freely, when you need anti-collision lighting, and when night rules kick in.
Location is used once to look up today's sun times and is never stored.
