Congratulations, Sean!
And in another coincidence, there is a full eclipse of the moon (at least in the SF Bay area, where I live) on October 8th, my anniversary! Unfortunately from 2 to 4 AM, but I think I'll get the wife up and tell her how I move the heavens and the earth to celebrate our
union!

From the USNO website:In the northern hemisphere, at latitude 5 degrees the dates of equal day and night occur about February 25 and October 15; at latitude 40 degrees they occur about March 17 and September 26. On the dates of the equinoxes, the day is about 7 minutes longer than the night at latitudes up to about 25 degrees, increasing to 10 minutes or more at latitude 50 degrees.I live at 37°N. September 26th is my birthday. :)
