All countries with daylight saving time

Dates for the time change

The change from summer time (in English "Daylight Saving Time") and winter time (the standard time) takes place in each country according to individually defined rules. For example, in Germany this is always at 2 a.m. on the last Sunday in March and at 3 a.m. on the last Sunday in October.

Within the EU, it has been agreed that time changes will actually be carried out at the same time, even in different time zones. For example, Portugal (Western European Time) and Finland (Eastern European Time) change the clocks at the same time. It is 2 a.m. in Portugal and 4 a.m. in Finland.

However, this agreement does not exist everywhere. The Brazilians set their clocks to winter time as early as February, while in neighboring Paraguay they wait until the end of March. In nearby Chile, people wait until April or even May.

Winter time is summer time in the southern hemisphere

Due to the path of the sun between the northern and southern tropics, the seasons also shift depending on their position on the globe. In the southern hemisphere, the sun is closer in December than in the northern hemisphere. At the time of the European winter months, it is summer there. As a result, in the southern hemisphere we switch to summer time, while we switch to winter time.

Abolition of summer times

The changes between summer and winter times are not without controversy. Many countries no longer take part in the time change. Countries near the equator do not need them anyway due to the year-round similar sun position. The real goal of summer time is to make better use of daylight. The effect was particularly noticeable financially when the coffers were empty in the post-war period and during the oil crisis in the 1970s.

The savings effect is now largely disproved. Instead, DST twice a year causes problems for many people. Children in particular need up to a week to adjust their internal clock. Problems also arise in agriculture because, for example, dairy cows can cope with changed milking times even worse than humans.

On the other hand, it has also been proven that more sunlight also produces more vitamins, causes less depression and the bottom line is that people feel more comfortable. In fact, the time change brings us 1 hour more sunlight - if you don't get up late and go to bed early.

The discussions about the pros and cons of the time change take place worldwide. Russia has meanwhile said goodbye to summer time and Turkey has declared it year-round. Other countries have also partially or completely abolished summer time in recent years.

In 2018, the EU Commission carried out an online survey on the abolition of the time change. Around 84% of the 4.6 million participants were in favor of abolishing the time change. However, an overwhelming proportion of the vote came from Germany. As a result, the Commission planned to abolish summer time as early as April 2019. However, after the EU member states considered this time frame to be too short-term, the Commission rowed back. The new date should be March 28, 2021 - however, the European Commission did not manage to agree on a uniform approach in good time.
