I know the days get shorter every winter. That’s not my question.

My question is this:

My father has been keeping track of when the sun sets each evening for many years. And the last couple of years the sun sets earlier than it used to.

In the past, the earliest time of the year when the sun would go down behind the mountains was around 1 PM in the afternoon. This would happen around Christmas.

But at some point in recent years, this changed. Now the sun already sets behind the mountains at 1 PM at the end of November. Which means that around Christmas, the sun sets noticeably earlier than it used to.

I don’t keep track of this, but I think he’s right.

​

So how is that possible?
