Do I need to change my phone and computer manually?

No. Any device that syncs its time over the internet updates itself. Car clocks, ovens, microwaves and older wall clocks usually need doing by hand.

End: 2027-10-31
Location: Slovenia

2027 time change dates for Slovenia

Clocks go forward: Sunday, March 28, 2027

At 2:00 AM the clocks jump straight to 3:00 AM in Slovenia. That hour never happens, and everyone loses an hour of sleep.

Clocks go back: Sunday, October 31, 2027

At 3:00 AM the clocks return to 2:00 AM, so that hour is lived through twice and the night is an hour longer.

Slovenia keeps CET in winter and shifts one hour forward for the summer.

Health Considerations for Slovenia Residents

The spring transition is the one that hurts. A study in Open Heart found the risk of heart attack rose by about 24% on the Monday after clocks went forward, before falling back to normal within the week. Research published in Current Biology found a 6% rise in fatal traffic accidents in the week following the spring change, with the effect strongest in the morning and in the western parts of time zones.

The autumn change, when most people gain an hour, shows no comparable spike. Researchers attribute the difference to sleep loss rather than to the clock change itself.

Health Tip: Shift your bedtime 15 minutes earlier each night for the four nights before the spring change, so the hour is absorbed gradually rather than lost all at once.

Technology and Time Changes in 2027

Phones, computers and anything else that syncs with an internet time server handle the transition on their own. What still catches people out in Slovenia is the long tail of devices that don't: car dashboards, ovens and microwaves, wall clocks, older thermostats, and cheap alarm clocks with a DST setting hard-coded to a schedule that has since changed.

For anyone running servers, the transitions are a recurring source of bugs — duplicated or missing local timestamps around the changeover, cron jobs that fire twice or not at all, and stale operating system timezone databases. Storing timestamps in UTC and keeping the tzdata package current avoids almost all of it.

Background

Germany and Austria-Hungary were the first countries to adopt DST nationally, in April 1916, as a wartime fuel-saving measure.
The Uniform Time Act of 1966 ended a chaotic period in which US cities set their own clock-change dates, and established a uniform national schedule.
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.

Tips for Slovenia

💡

Be extra cautious driving the Monday after the spring time change - accident rates increase.

💡

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 Slovenia in 2027?

Clocks go forward on Sunday, March 28, 2027 and back on Sunday, October 31, 2027.

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.
