The season's shortest day

When is winter solstice 2017? Here's your guide to the shortest day of the year

That is because at the solstice, Earth's tilt means that the "terminator" - the line dividing day and night that can be seen in pictures taken from space - crosses the country diagonally.

During the winter solstice, sunlight should shine into a special chamber at sunrise.

The winter solstice is arriving on December 21, which has been announced by the National Aeronautics and Space Administration (NASA) to be among 2017's longest solar days, with the shortest period of sunlight and longest period of night.

The solstices, and the seasons they mark, are the result of a celestial coincidence.

"It is how we connected sites like Munster Joinery's offices in Ballydesmond and we are delighted it has now led to our involvement with Newgrange and the winter solstice", he said.

The shock revelation has finally disclosed the true aim of the mysterious Advanced Aerospace Threat Identification Program. Bigelow told the Times that, "Internationally, we are the most backward country in the world on this issue".

More than a few ancient human cultures celebrated this time as the day the Sun returned from its waning beginning instead a period of longer days. But that usually doesn't make the solstice the coldest day of the year, or put it in the middle of winter. It also marks the longest day of the year in the Southern Hemisphere. That precision is a reflection of the fact that the solstice is actually calculated by a measure other than day length. For weather forecasters, winter begins on December 1 and lasts until February 28 or 29.

The word solstice literally means, in Latin, that the sun is standing still. During the other half of the year, between September and March, the south pole is pointing toward the sun, with the solstice marking the midway point of this journey. It's also the day when the Northern Hemisphere has the shortest amount of day (least amount of sunlight).

Is the solstice on the same day every year?

This extra quarter day is why we add a day to the calendar every four years with a leap year - to stop the dates drifting gradually through the seasons.
