2025 schedule

Estonia keeps EET in winter and shifts one hour forward for the summer.

Health Considerations for Estonia 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.

Technology and Time Changes in 2025

Phones, computers and anything else that syncs with an internet time server handle the transition on their own. What still catches people out in Estonia 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.

Agricultural Considerations

The story that DST was introduced for farmers has it exactly backwards. Farmers in Estonia 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were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.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.

Getting ready

• Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
• 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!
• Remember that not all countries change on the same date - check international meeting times carefully.
