Hi everyone,
Just reading through the 83 Goldbox again, this time with a focus on astronomy, time, seasons, etc. I have several things that I can't make heads and tails of:

• Why does Greyhawk/Oerek have 12 month? If Luna makes exactly thirteen cycles a solar year (364 days), wouldn't the cultures have developed a 13 month system? (referring to the baseline data sheet in the Glassography)
• When adjusting the baseline data sheet for latitude it says "For each degree of latitude adjust away from the baseline, the times should be adjusted by two minutes, adding if above 40° north and subtracting if below" This refers to the sunrise/sunset times (the only "times" on the baseline data sheet) Seems more like a longitudinal? Is this a mistake? Adjusting for latitude is of course also important but should work very, very differently.
