Time Change Latvia 2028

2028 time change dates for Latvia

At 3:00 AM the clocks jump straight to 4:00 AM in Latvia. That hour never happens, and everyone loses an hour of sleep.

At 4:00 AM the clocks return to 3:00 AM, so that hour is lived through twice and the night is an hour longer.

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

Health Considerations for Latvia 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.

Does DST Actually Save Energy?

This was the original justification, and it is the claim that has held up worst. A US Department of Energy report to Congress in 2008 measured the four weeks added to DST in 2007 and found a saving of about 0.5% of daily national electricity use — real, but small.

Other work has found no saving at all. A well-known study of Indiana, which adopted DST statewide in 2006, found residential electricity use actually rose by 1–4%: households used less lighting but more air conditioning on hot summer evenings. Any lighting savings are also partly offset by extra petrol use as people travel more in the lighter evenings.

Background

• 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.
• 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.
• 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.

Agricultural Considerations

The story that DST was introduced for farmers has it exactly backwards. Farmers in Latvia 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.
