Just a reminder that Daylight Saving Time (in the United States) for 2016 begins at 2:00 AM on Sunday, March 13 and runs until 2:00 AM on November 6.

Daylight saving time (DST) (happily called “summer time” in British English and European official terminology) means we advance our clocks to “spring ahead” into summer.

Afternoons and early evenings have more daylight and mornings have less.

This practice goes back to 1895 and many countries have used it since then, though with varying details.

All kinds of benefits are claimed for the practice. In the early days of DST, it was done to reduce evening usage of incandescent lighting (a big use of electricity then), and to add extra daylight hours to retailing, sports, and other activities that exploit sunlight after working hours.

You might get some extra sunshine which is good for some natural Vitamin D. Sufferers of seasonal affective disorder (SAD) may find some relief, but clock shifts also disrupt sleep patterns and some people’s circadian rhythm. It is often suggested that you turn your clock ahead in the early evening the night before (tonight) and just lose an hour and go to sleep as usual as a way to transition, rather than waking up to setting it back and losing an hour. Of course, many of our devices do the adjusting automatically now, and if traveling to other time zones doesn’t mess you up, this is probably no big deal.
