Since most people in the United States just changed their clocks again, it seems like a good time to ask: should we keep doing that? Or should we just pick a time and stick with it?

"Solar noon" is the time when the sun is at its highest point in the sky, halfway between sunrise and sunset. During Standard Time, solar noon happens at approximately 12:00 (clock noon). During Daylight Saving Time, solar noon happens at approximately 1:00.

(I say "approximately" because the exact time depends how far east or west you are in your time zone.)

Hawaiʻi and (most of) Arizona have already switched to permanent Standard Time. Should the entire country do the same, or switch to permanent Daylight Saving Time, or continue switching between them two times per year?
