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

Like I do almost each time Daylight Saving Time ends or starts, I have collected together a handful of short video descriptions about why we have Daylight Saving Time. Take a look and see if there is one that can help you describe Daylight Saving Time to your students..
National Geographic has actually 2 videos titled Daylight Saving Time 101. The very first one, released in 2015, is a bit more positive than the 2nd one that was published in 2019. Both variations are embedded below..

Daylight Saving Time ends today for a lot of my pals 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 modification as Ill see the sun an hour previously. And ideally, my kids will benefit from the “extra” hour of time for sleeping next Saturday night.

If it isnt as concise as the videos above, CGP Greys video explanation of Daylight Saving Time is still an excellent one even.

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