Countdown to the next change
Background
- Arizona and Hawaii are the only US states that skip DST statewide, along with the territories of Puerto Rico, Guam, American Samoa and the US Virgin Islands.
- Germany and Austria-Hungary were the first countries to adopt DST nationally, in April 1916, as a wartime fuel-saving measure.
- The energy case for DST is weak by modern standards. A US Department of Energy study in 2008 found savings of about 0.5% of daily electricity use, and other studies have found no saving at all.
Tips for Japan
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Check and replace smoke detector batteries when changing clocks - it's a good reminder!
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
Frequently asked questions
When do the clocks change in Japan in 2025?
They do not. Japan does not observe Daylight Saving Time.
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.
