Sunrise, sunset, and the 30-minutes-before-and-after window most states use for legal shooting light — for any spot, any date.
Most whitetail states define legal shooting hours as 30 minutes before sunrise to 30 minutes after sunset — that's what this tool shows. A handful differ (some waterfowl seasons, some states use exact sunrise/sunset), and printed times in your regulations always win. Check your state's current regs before you climb in.
Times are computed astronomically for your exact coordinates and shown in your device's local time zone, so they already account for where you sit inside your time zone — often 10–20 minutes different from the newspaper times for the nearest big city.
