Daylight Saving Time Ends in the United States

Day:

• Daylight Saving Time (DST) typically ends on the first Sunday in November.
• The clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time.

History:

• Concept attributed to Benjamin Franklin (1784), modern DST proposed by George Vernon Hudson (1895), and William Willett (1907).
• First implemented during World War I to conserve energy.
• Uniform Time Act of 1966 standardized the start and end dates of DST in the US but allowed states to opt-out.
• Energy Policy Act of 2005 extended the duration of DST starting from 2007, currently March to November.

Traditions and Activities:

• No specific traditions; it is a practical change rather than a cultural event.
• People generally use this time to remember to change batteries in smoke detectors and other household maintenance tasks ("Change your clock, change your battery").
• Some individuals take advantage of the extra hour of sleep gained on this night.

What People Do:

• Reset their clocks back one hour before going to sleep on Saturday night or upon waking up on Sunday.
• Adjust schedules accordingly for activities, such as church services or brunch plans, which may be affected by the time change.
• Businesses must update their operating hours if they open early or close late.

Remember that not all areas in the United States observe Daylight Saving Time; states like Arizona (except for the Navajo Nation) and Hawaii, and some territories like Puerto Rico do not participate.
