This is super rough...I'm basically giving each episode a rough date. More like a 7 day period it could fall under.
Based on the entirely accurate and very specific science of horoscopes, I've determined that Jim is probably a Scorpio-Sagittarius cusp, meaning that this episode takes place between the 18th and 24th of November. It couldn't be the weekend of the 21st and 22nd, and it's likely not the preceding Friday either. So it's on one of 4 days, the 18th, the 19th, the 23rd, or the 24th.
I am nigh certain about the date on this one, provided the year. Last Friday before Christmas, so it's gotta be the last day before break, which makes sense for a number or reasons, not the least of which being the fact that Christmas is never shown.
