Probably not exactly what your looking for, but our home has a number of lights on timers that turn on at roughly dusk and turn off at our nominal bed time. I adjust them a few times a year as the days get longer and shorter. My wife of 40 years, an otherwise smart and wise woman, cannot comprehend why we don't need to change the timers by an hour when Daylight Savings Time starts and ends. I tell her that the sun doesn't know what time it is, but it doesn't help. Twice every year.
- rambambram 4y agoGreat anecdote! I'm in the process of learning my 4 year old nephew what a day, a month and a year are. And then I also tell him that a week is just something that people invented for convenience.
- dragonwriter 4y agoWeeks are equally arbitrary to months (and retain a closer tie to the cycle motivating both.)
- rambambram 4y agoCan you expand on that? Not for my nephew, but for me. ;)
- dragonwriter 4y agoBoth month (full cycle) and weeks (quarter cycle) are related to the lunar cycle (“month” is also closely etymologically related to “moon”). But months in the Roman calendar (impacting derivatives of that calendar) got lengthened a bit to fit an arbitrary preference for ratio to the solar cycle with days further moved between them for a variety of reasons, while weeks stayed the same.
- rambambram 4y agoThanks. My main point still holds true, I think. Days, months and years are based on celestial bodies. Weeks are derived from that. Correct me if I'm wrong!
- HWR_14 4y ago> Weeks are equally arbitrary to months In the dominant Gregorian calendar and its predecessors. There are others where this is not true.

- stevage 4y agoBut if they turn off at your nominal bed time, isn't that bed time based on the clock, which is affected by daylight savings?
- programmer_dude 4y agoFYI you can get devices which can detect low day light conditions and automatically switch your lights on.
- gnicholas 4y agoI love that the Wemo app can be programmed to trigger events X minutes/hours before/after sunrise/sunset. Before this feature was added I did have to change the schedule when DST started/ended (because unlike your timers, these schedules were tied to clock time).
