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

TED-Ed has 2 lessons that arent specifically about Daylight Saving Time however are associated to the subject. The History of Keeping Time describes sundials, hourglasses, and the development of timezones.

If it isnt as concise as the videos above, CGP Greys video description of Daylight Saving Time is still a good one even.

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

The Telegraph has a 90 second explanation of Daylight Saving Time. The video doesnt have any narrative so it can be seen without sound.
