Daylight saving time (DST) is the convention of advancing clocks as afternoons have more daylight and mornings have less. The savings come from reduced electricity usage in the evening – when lights don’t need to be switched on until later.
To facilitate this, clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. This method is widely used in Western countries as a way to save energy. It is believed that this act of advancing the clocks by an hour during the summertime saves considerable energy/electricity, variously put at one per cent, if not more. We will never know what benefits, until we try this.
Shame! We have to be still thinking of this while the rest of the world
has it already. Our system is kind of chaotic, but we do have an order and a rhythm to that chaos.
