The sun is every day exactly South on a different time if you want to be
very exact. After 4 years the pattern repeats itself moer or less, but if
you want it exact it will be shifted a little bit.
But I calculated for this century the mean timeequation for each date and
you can use that to find out how much noon is from direct South.
Look at http://www.chabot.demon.nl/sundials/sunmeangmt.htm, there is also a
downloadable file with the values which you can find at

Hi:
I've been marking the ceiling exactly at noon PST and just also started to
include noon PDT.
It would be interesting to add a line for when the Sun is South and for
the equinox.
Can someone email to me a list of for each day for a year from now the
exact time when the Sun is South?
The mirror on the windowsill is at: 123:09:50.5 N, 39:11:24.6 W, 900 feet
above mean sea level.
Have Fun,
