The Telegraph has a 90 2nd description of Daylight Saving Time. The video does not have any narration so it can be viewed without noise.

Daylight Saving Time ends today for much of my buddies in Europe and it ends next Sunday for those people in North American states and provinces that observe Daylight Saving Time. As somebody who gets up early and resides in a northern state, I invite the change as Ill see the sun an hour previously. And ideally, my kids will make the most of the “additional” hour of time for sleeping next Saturday night.

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

Like I do practically whenever Daylight Saving Time ends or begins, I have congregated a handful of brief video descriptions about why we have Daylight Saving Time. Take a look and see if there is one that can help you discuss Daylight Saving Time to your trainees..
National Geographic has actually 2 videos entitled Daylight Saving Time 101. The first one, published in 2015, is a bit more positive than the 2nd one that was released in 2019. Both versions are ingrained below..

CGP Greys video explanation of Daylight Saving Time is still a great one even if it isnt as succinct as the videos above.
