longest day

[Frank Evans]

Mea culpa! I should have attended to the Royal Society motto: "nullius 
in verba" (don't believe a word of it!) and not taken someone else's 
word that the longest day of the year was in September. My grateful 
thanks to those who pointed out that it is close to 22 December and is 
about 24 hours and 30 seconds. The shortest day is around 26 March at 23 
hours 42 Seconds. And, as Kevin Karney tells us, the Greeks were on to this.
