- You probably do not need a sunrise alarm clock for a 7:00 am start here: only 0 weekday mornings are still properly dark. If you get up earlier, check the hour against the sunrise times in the table below.
- Daylight alone gives little reason for a light therapy lamp here. Getting outside in the 6:48 am to 4:46 pm window on the shortest day does more than most people expect.
- If you head home at 5:30 pm, the sun has already set from Nov 2 to Feb 10: worth checking your bike lights and porch light before Nov 2.
