Daylight Saving Time: 2023

March 9, 2023


Most of us will set our clocks an hour forward on Sunday at 2 a.m. WHY?
HINT: It has nothing to do with helping farmers.

3 Things To Know About Daylight Saving Time (DST)

  • Not intended to make longer days for farmers, but rather first enacted to help conserve energy used for light/heat (coal) during WWI.
  • The need for DST has always been a topic of debate. Today, about 70 countries observe DST – that’s less than 40% of countries around the world.
  • Daylight saving time lasts approx. eight months. Standard time lasts four months.


  • The federal government mandated daylight saving time (DST) in 1918 during WWI, and again during WWII.
  • 1966: Congress standardized DST start and end dates requiring observing states to be in sync, but allowed states to opt out.
  • 2005: Congress reset the start of DST to the second Sunday in March and set the end of DST for the first Sunday in November; these changes went into effect in 2007.

Did You Know?

States are not required to observe DST, but congressional approval is required to keep year-round daylight saving time.

  • As of Oct. 2022, 19 states have passed laws to keep year-round (permanent) daylight saving time over the past several years. These laws await Congress’ approval.
  • Two states – Arizona (except Navajo territories) and Hawaii – as well as five major U.S. territories, don’t observe DST & keep year-round standard time.
“This ritual of changing time twice a year is stupid. Locking the clock has overwhelming bipartisan and popular support. This Congress, I hope that we can finally get this done.”

Sen. Marco Rubio (R-FL) said in early March. He has introduced and reintroduced legislation since 2018 to eliminate the time shift and make daylight saving time permanent. In 2022, the bill – “The Sunshine Protection Act” – passed unanimously in the Senate though never made it to a vote in the House.

Changing our clocks was controversial from the beginning with complaints about BIG government. According to a 2022 poll by CBS News, less than a fourth of U.S. residents like switching the clocks twice each year, while nearly half would prefer permanent DST. Meanwhile, about a third of people prefer permanent Standard Time. What would you prefer? See if your state has pending legislation on our source page.
