What to do about it in Round Rock
- A sunrise alarm clock is worth getting here: on 77 weekdays the sun is still at least 20 minutes from rising at 7:00 am. Dark mornings run from Aug 20 to Apr 16, so set it up before Aug 20.
- Daylight alone gives little reason for a light therapy lamp here. Getting outside in the 7:24 am to 5:34 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 25 to Dec 9: worth checking your bike lights and porch light before Nov 25.
