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.
- Roughly 70 countries use some form of DST, but they are concentrated in Europe and North America. Most of Africa and Asia do not.
- Benjamin Franklin is often credited with inventing DST, but his 1784 essay was satire — he joked that Parisians could save candles by waking earlier. The modern proposal came from New Zealander George Hudson in 1895 and Briton William Willett in 1907.
Tips for Thailand
Remember that not all countries change on the same date - check international meeting times carefully.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Frequently asked questions
When do the clocks change in Thailand in 2027?
They do not. Thailand 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.
