The official start of fall is just around the corner, and it comes with shorter days and longer nights. On Sunday, Nov. 3, we will once again say goodbye to daylight saving time and welcome the return to standard time.

Daylight Saving Time is implemented in all U.S. states except Arizona and Hawaii. Versions of Daylight Saving are also observed, or partially observed, in many other countries—including most of Europe, Mongolia, Australia, New Zealand, Egypt, Israel, Brazil, Chile, Paraguay, French Guiana, Cuba, and Haiti.

Not long from now, you'll lose an hour of daylight in the evening. Here's when you have to set your clocks back.
