Yep, today is the shortest day of the year. After today, the days start getting longer. But, we have to get through our coldest period yet, mid-January, when we'll also be at our closest approach to the Sun (Jan 4th).

I'd say the Sun gods were smiling down on Newgrange today when the previous 3 days fog lifted in time to give those lucky enough to be there, the chance to view the most rare of archeological events - the shining of sunlight into its passage tomb on this day each year. They (gods) were just taking the piss until this morning! :D

Just to confuse things even more, the EARLIEST SUNSET occured a week ago and the LATEST SUNRISE wont occur for another week.

This is because the Declination of the Sun is changing in "real time" and
also the "Equation of Time" is changing. (Because of the non circular orbit of the Earth and the obliquity of the ecliptic.)

It is a moving dynamic system.

Think of an accordian player swaying sideways as he/she pushes the accordian bellows closest together.

Forgot to mention.

If you could see the the bottom of the Analemma (the figure 8 "thing" in Anthony's side photo) you would notice that the LOWEST Sun does not coincide with the BOTTOM of the Figure 8.

Work THAT one out !

Just to stick my 2 cent worth.
<soapbox>
The solstice is a point on the ecliptic - the date/time at which the sun passes throught this point is generally around 21/22 Dec. - the calendar being artificial the date/time wobbles around quite a bit. In general the calendar is a poor marker of time - after all "New Years Day" is not for ten calendar days yet and the premier midwinter festive day celebrating birth is still 4 calendar days away. So its off a bit!!
Having said that the chamber thing at newgrange happens for 7 to 10 days each side of the solstice event and 'peaking' at the morning closest to it.
</soapbox>

Still happy new year, mid-winter, year-rollover or whatever.
