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

TED-Ed has 2 lessons that arent specifically about Daylight Saving Time but are related to the topic. Initially, The History of Keeping Time explains sundials, hourglasses, and the development of timezones.

Daylight Saving Time ends today for much 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.

The Telegraph has a 90 second description of Daylight Saving Time. The video doesnt have any narrative so it can be watched without noise.
