With the arrival of October, the question of when the time is changed every year.
However, the change of time, the second by 2021, will not reach the last weekend of the month.
Specifically, the winter time will begin on Saturday 30 to Sunday, October 31.
In this way, at dawn we will have to modify the clocks so that at 03.00 hours again mark 02.00 hours (peninsular hours).
Thus, Sunday will have an hour more.
During the winter time, it will dawn and dusk before.
In Spain it dawns between 08.00 and 08.30 and dark between 17.30 and 6:00 p.m., both cases taking as a reference the schedule of Madrid.
Change to winter schedule can bring some symptoms, especially in the most vulnerable population, such as children or older people.
These range from drowsiness or fatigue to lack of attention.
