Sleep an hour longer: Some people may be happy about the change from summer to winter time. But be careful: you shouldn't forget a special watch.
On Sunday, October 27th, normal time begins again, or in other words: winter time. At three o'clock in the morning the clocks are set back – to two o'clock. However, most people shouldn't have to turn too many clocks. Many now switch over automatically: usually and with the appropriate settings, such as those on smartphones and laptops – and of course smartwatches and radio alarm clocks.
One clock that is particularly worth checking on Sunday: the heating system. According to the German Liquefied Gas Association, they often do not switch to winter time on their own. So it's better to check whether everything worked or whether the heating will stop for an hour in the future.
In order for functions such as night setback to continue to work as they should, you would have to change the time manually. Otherwise, the night reduction no longer ensures the right room temperature at the right time in the evenings and mornings – but rather works in response to the respective requirements.
If the heating continues to run in summer time mode, it will start at 6 a.m. on weekdays from October 27th, for example, instead of 7 a.m. as desired. In the evening, the heating output is reduced an hour too early, instead of around 10 p.m. at 9 p.m.
The night reduction is intended to ensure that in those hours in which less heat is required, i.e. at night, there is automatically less heating than during the day. This also means less energy is consumed.
