2024 time change dates for Poland
At 2:00 AM the clocks jump straight to 3:00 AM in Poland. That hour never happens, and everyone loses an hour of sleep.
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.
Poland keeps CET in winter and shifts one hour forward for the summer.

Economic Impact of DST in Poland
The economic effects of Daylight Saving Time in Poland are real but modest, and studies disagree on their size. Retailers and hospitality businesses generally favour DST, arguing that lighter evenings encourage shopping, dining out and other after-work spending — the US retail lobby was one of the main forces behind the 2005 extension of the DST period.
The transitions themselves carry a cost. Research from Chmura Economics has put the one-off economic cost of the spring change in the United States at roughly $430 million a year, driven by lost productivity, workplace injuries and the health effects of a disrupted night's sleep.
Technology and Time Changes in 2024
Phones, computers and anything else that syncs with an internet time server handle the transition on their own. What still catches people out in Poland 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
- Russia experimented with permanent summer time from 2011 to 2014 before settling on permanent standard time.
- 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.
- The spring transition is associated with a measurable short-term rise in heart attacks and fatal traffic crashes, an effect researchers attribute to the lost hour of sleep rather than the clock itself.
Agricultural Considerations
The story that DST was introduced for farmers has it exactly backwards. Farmers in Poland and elsewhere were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.
The reason is straightforward: farm work follows the sun, not the clock. Moving the clock forward just means doing the same work an hour earlier by the clock, while deliveries, markets and hired labour all shift with it. Dairy farmers make the point most often, since cows keep to their own schedule and take several days to adjust to a changed milking time.
Tips for Poland
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Set your clocks before going to bed to avoid confusion in the morning.
Check and replace smoke detector batteries when changing clocks - it's a good reminder!
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Frequently asked questions
When do the clocks change in Poland in 2024?
Clocks go forward on Sunday, March 31, 2024 and back on Sunday, October 27, 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.
