A few months ago we switched off Daylight Saving Time (“DST”) and re-entered the normal time pertaining to our timezone on planet Earth. In this article I commented how the adjustment of an hour actually exacerbates the (perceived) problem of darkness and uses up daylight hours in the summer.
As we approach the winter solstice (21 December 2016) I see the same thing happening again, but now on a natural footing.
After the winter solstice the days begin to get longer because the angle of the Earth’s axis of rotation with respect to the sun decreases (i.e. increasingly points towards it). The trouble is that Winter begins on the winter solstice, and as a meteorologist will tell you…this is when it gets cold.
(Note that I’m ignoring here the meteorological definition of Winter which is defined as starting from 1 December. I have no problem here; we ignore the weather forecast due to inaccuracies so I’m happy to do the same here with their unastronomical definition of the seasons! 😉 )
The bottom line is that this means we have increasingly longer days in which to be miserable about the cold weather.
At this point I should note that our friends the meteorologists will tell us that the reduced temperatures continue reducing after the winter solstice because of a thermal lag (“lag” here as in “behind”, not thermal lagging as in “padding around a hot water cylinder”). Lag doesn’t explain a reduction of temperature prior to the winter solstice!
So what is it with daylight saving time then? Should we use the model as a basis to implement a temperature saving time? Or do we use DST in an effort to emulate nature’s natural clock which appears to be playing a joke on us?

An old post, but indeed Standard Time starts less than two months before Winter Solstice, while it ends just shy of three months after. So we do indeed have a lag.
I am more curious about why it’s NOT evenly split before and after.
