When Does Daylight Savings End 2015: Time & Clock Change

Daylight Saving Time ends at 2 a.m. Sunday, Nov. 1, which means you will need to turn your clocks back an hour before you go to bed Saturday night Oct. 31. The annual tradition signals the official start of shorter days and, on Nov. 1, sunset will be around 5:08 p.m. CST. The days will get shorter from there.

Daylight Savings facts & annual time/clock change:

  • Benjamin Franklin started Daylight Savings. In his essay entitled “An Economical Project for Diminishing the Cost of Light”, Franklin suggested “people could save candles by getting up earlier and making better use of available light”. In 1907, William Willett championed the idea.  It was brought to the United States by way of a businessman from Pittsburgh named Robert Garland, a who first came upon the idea while in England.
  • DST started when “war time” was established in the U.S. in 1918 to save fuel during World War I.
  • In 1999, the time change disrupted terrorist plans for a bombing in Israel.The West Bank was on Daylight Saving Time while Israel had just switched back to standard time. The time change confused the terrorists. The bombs were planted, but detonated an hour early, killing three terrorists.
  • On August 8, 2005, President George W. Bush signed the Energy Policy Act on that day, setting the official end time for DST as the first Sunday in November. From 1986-2006, Daylight Saving Time began on the first Sunday in April and ended on the last Sunday in October.
  • In Antarctica, there is no daylight in the winter and months of 24-hour daylight in the summer.
  • To keep to their published timetables, trains cannot leave a station before the scheduled time. So, when the clocks fall back one hour in October, all Amtrak trains in the U.S. that are running on time stop at 2:00 a.m. and wait one hour before resuming. Overnight passengers are often surprised to find their train at a dead stop and their travel time an hour longer than expected. At the spring Daylight Saving Time change, trains instantaneously become an hour behind schedule at 2:00 a.m., but they just keep going and do their best to make up the time.
  • Hawaii and Arizona do not participate in Daylight Savings. In a virtually unanimous vote, Arizona legislators agreed to opt out of daylight-saving time in 1967.
  • In the spring, that hour of lost sleep due to the Daylight Saving switch has been linked to an increased risk of heart attacks. On the other hand, the risk of heart attacks fell by 21 percent later in the year when an hour was added back to the clock.
  • Daylight Savings is at 2 a.m. because according to Live Science, that’s considered to be the least disruptive time of day.
  • 27 percent of Americans said the time changes either makes them early or late for an appointment.
