2024 time change dates for Iowa
At 2:00 AM the clocks jump straight to 3:00 AM in Iowa. That hour never happens, and everyone loses an hour of sleep.
At 2:00 AM the clocks return to 1:00 AM, so that hour is lived through twice and the night is an hour longer.
Iowa keeps CST in winter and shifts one hour forward for the summer.
Countdown to the next change
Background
- Germany and Austria-Hungary were the first countries to adopt DST nationally, in April 1916, as a wartime fuel-saving measure.
- Roughly 70 countries use some form of DST, but they are concentrated in Europe and North America. Most of Africa and Asia do not.
- The Energy Policy Act of 2005 extended US DST by four weeks starting in 2007, moving the start to the second Sunday in March and the end to the first Sunday in November.
Tips for Iowa
Remember that not all countries change on the same date - check international meeting times carefully.
Gradually adjust your sleep schedule a few days before the time change to minimize disruption.
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Frequently asked questions
When do the clocks change in Iowa in 2024?
Clocks go forward on Sunday, March 10, 2024 and back on Sunday, November 3, 2024.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
