Waking and coming home in the dark

With a 7:00 am alarm, the sun is not yet up on 156 weekdays a year. Heading home at 5:30 pm, it has already set on 0. 0 weekdays start and end in the dark. The alarm and lamp guide shows how that compares across the country.

What to do about it in Alamo

• A sunrise alarm clock is worth getting here: on 60 weekdays the sun is still at least 20 minutes from rising at 7:00 am. Dark mornings run from Aug 5 to Apr 23, so set it up before Aug 5.
• Daylight alone gives little reason for a light therapy lamp here. Getting outside in the 7:16 am to 5:46 pm window on the shortest day does more than most people expect.
• Heading home at 5:30 pm, you get at least some daylight all year here.
