Sun is setting on California's Daylight Saving's Time...

48. Not me

I use the same amount of light day after day because I have used lamp timers for decades. And anyone living in a densely populated urban area or in an apartment with little access to sunlight, is going to put lights on regardless of whether it is standard or daylight savings time.

The bigger issue, which has somewhat been brought up in this thread, is that the outdoor light availability is not only going to vary depending on where you are in a timezone region, but also your latitude. For those who live in the furthest north of the CONUS, the amount of daylight can approach 20 hours in summer and only 4 in winter (where I live in Philly, the longest day length is about 15 hours in summer and only 9 in winter). I remember a couple of trips to Detroit in the summer (which is on the western edge of ET) and was surprised to see the sun setting at like 9:30pm, where here in Philly, it was setting almost an hour earlier. I think this may have been a similar issue with Indiana being on that western edge of ET too. And in places like Hawai'i, which is closer to the equator than the CONUS, the day length varies very little, which is probably why they don't use DST.

There has been much written about "SAD" (Seasonable Affective Disorder), where "light therapy" is often suggested, so you have some people using high intensity lights in fall through winter and into spring.

So wholesale ascribing some "benefit" to continually changing the time and messing up sleep routines, is disingenuous when you look at all the variables!
