TED-Ed has two lessons that arent specifically about Daylight Saving Time however are associated to the topic. The History of Keeping Time explains sundials, hourglasses, and the development of timezones.

CGP Greys video description of Daylight Saving Time is still an excellent one even if it isnt as succinct as the videos above.

Daylight Saving Time ends today for a number of my buddies in Europe and it ends next Sunday for those of us in North American states and provinces that observe Daylight Saving Time. As someone who gets up early and lives in a northern state, I welcome the change as Ill see the sun an hour earlier. And hopefully, my kids will benefit from the “extra” hour of time for sleeping next Saturday night.

Like I do practically every time Daylight Saving Time ends or begins, I have actually gathered together a handful of short video explanations about why we have Daylight Saving Time. See and take an appearance if there is one that can help you discuss Daylight Saving Time to your trainees..
