Mark your calendars: Its almost time to set your clocks ahead one hour as we spring forward into Daylight Saving Time this Sunday, March 9, at 2 a.m. Tired of changing your clocks? Youre not alone. Both President Donald Trump and senior adviser Elon Musk have said they want to end the annoying seasonal time changes, by making Daylight Saving Time (DST) permanent (meaning that after setting our clocks forward, we would not set them backward anymore).Thats in line with a 2023 YouGov poll that found nearly two-thirds (62%) of Americans want to end the practice, though only half prefer to keep DST permanent versus keeping Standard Time permanent (meaning we would not set our clocks forward anymore).As president, Trump previously indicated support for such a change,tweetingin 2019, Making Daylight Saving Time permanent is O.K. with me! He seemed to reiterate his stance in December, posting to Truth Social that once he was in office, The Republican Party will use its best efforts to eliminate the time changes, which he called inconvenient, and very costly to our Nation. (Note: Its not clear exactly what Trumps stance was, as he wrote about eliminating Daylight Saving Time, not the time changes specifically. However, given his previous stance, many have interpreted it to mean eliminating the time changes.)On X, Musk posted a similar rallying cry, saying people want to abolish the annoying time changes!So far, the Trump administration hasnt moved forward on the issue. However, health experts say Trump and Musk, as well as lawmakers who support making DST permanent, have it backward. Instead, they argue, Standard Time should be made permanent.Here, we break down some arguments for sticking with Daylight Saving Time versus Standard Time permanently.Health experts say stick with Standard TimeThe American Academy of Sleep Medicine (AASM) also wants to do away with the time change, but supports replacing Daylight Saving Time with permanent Standard Time because it best aligns with the sun and our natural circadian rhythms.By causing the human body clock to be misaligned with the natural environment, Daylight Saving Time increases risks to our physical health, mental well-being, and public safety, said Dr. Muhammed Adeel Rishi, lead author of the academys position statement, published in the Journal of Clinical Sleep Medicine. Permanent standard time is the optimal choice for health and safety.Research backs that up, saying the one-hour change disrupts the bodys natural sleep-wake cycle, which regulates body temperature, hormone release, and alertness. That could explain why Daylight Saving Time transitions lead to a spike in traffic accidents.Sticking with Daylight Saving Time may make people happierIn the 2023 YouGov poll, those in favor of making DST permanent said they preferred later sunrises and sunsets, giving them more daylight at the end of the day.The most compelling reason to make Daylight Saving Time permanent is that it seems to make people happier, with research showing seasonal increases in sun time were associated with decreased mental health distress.Where does Congress stand on the issue?Daylight Saving Time was originally adopted as a wartime measure in 1942 intended to maximize daylight hours in the summer, and has long been unpopular with lawmakers who tried to make the time change permanent with the now-stalled 2023 Sunshine Protection Act. The bipartisan bill, sponsored by then-Florida Senator Marco Rubio, now Secretary of State, passed unanimously in the Senate but failed to pass in the U.S. House of Representatives because lawmakers could not agree on whether to keep Standard Time or Daylight Saving Time.Do all states observe Daylight Saving Time?While Americans in most U.S. states change their clocks, Hawaii and Arizona are two exceptions, with both keeping to Standard Time.When is the Daylight Saving time change in 2025?Daylight Saving Time in the U.S. begins this Sunday, March 9 at 2 a.m. local time, meaning people will lose an hour of sleep but gain an hour of sunlight. It always starts on the second Sunday in March, and ends on the first Sunday in November. This contrasts with the U.K. and European Union, where it begins on the last Sunday in March (Sunday, March 30 at 1 a.m.) and ends on the last Sunday in October (Sunday, October 26 at 1 a.m).
