Shortest Day
 
I always thought 21st December was the shortest day. Apparently when next year is a leap year then Dec 22nd is the shortest day. I never knew that so thought I would share it with you :)

Re: Shortest Day
 
This is an extract -
A quick look at sunrise and sunset times on successive days in March and September will show that the above dates do not coincide precisely with the times of equal day and night length. There is another factor to be considered which is that the orbit of the Earth around the Sun is an ellipse and not a circle. By Kepler's Law the Earth moves fastest when it is closest to the Sun (approximately 3 January each year) and slowest when it is furthest away (approximately 4 July ). This 'unequal motion' causes variations in the length of the solar day and in the times of sunrise and sunset. -

Equinoxes and solstices : Time & timekeeping : Fact files : Learning : NMM

I'm not much wiser from reading it either :rolleyes:

Happy Yule and Solstice folks:Banane35:

Well fancy that then.

I still prefer to think of the 21st of June and December as being the longest and shortest days. Somehow the number 21 seems most appropriate.

It also means the longest day is 20th June next year as well:)
