Facts are chiels that winna ding!
If there are 10 hours of daylight in one day there are 10 hours of daylight in that day - Fact!
My problem is I never know which way to turn the clock, forward or back
I’m going to have one more try.
So, let’s talk accounts! I know you understand them!
We are going to put £100 in someone’s bank account.
In the first story, the person currently has a zero balance, so ends up with £100.
In the second story, the person is currently £10 in the red, so end up with £90.
In both stories, they were given £100, but in one of the stories, they end up with a smaller balance at the end.
The analogy isn’t perfect, but the thing is, someone who gets home from work at 6pm will have daylight longer in the evening if the sunset is at 10 o’clock than if it is at 9 o’clock. So when the clocks go back in autumn, this person’s evening light gets shortened by one hour.
Of course, in the financial analogy, those of us without day jobs or other clock constraints on our enjoyment of daylight are effectively being given cash in hand, so we all get £100 no matter what our bank balance was at the beginning of the story
