Most countries in Europe begin implementing annual winter time for 5 months starting on the 25th (Sunday) local time. The trading hours of the European financial markets will be delayed by 1 hour. The interest rate decision announced by the European Central Bank next Thursday will be announced at 20:45 Beijing time, and Governor Lagarde's press conference will be held at 21:30.

European countries unified the schedule at 1 a.m. local time on the 25th (Greenwich time) on the 25th, and the time was set 1 hour slower. After entering winter time, the local trading hours of Germany, Britain, and France for the three major European stock markets are still: London 8:00-16:30 and Paris and Frankfurt 9:00-17:30. The overall Beijing time corresponding to the trading period moved back 1 hour, that is, 16:00 to 00:30 the next day.

Since 1996, EU member states have moved back their clocks by one hour to implement daylight saving time every year on the last Sunday of March; on the last Sunday of October, they have set back their clocks by one hour to restore winter time. The design of the time change aims to make more use of sunlight to save energy.

As the European Parliament is still debating whether to cancel the conversion between winter time and summer time, it has not yet been decided how the time will change in 2021. This year may be the last time that Europe will enter winter time.
