I would pretty much pick the same as you. There is just something so fresh about them in January and the actual holidays are so far off at that point.I think in all honesty, the very first batch of MMC Special Days (Rudolph Day, Tom Turkey Day, JOL Day) might be the most important of the entire year. They really sort of "set the tone" for me mentally.
If I had to put together a "top 3" for months to have special days, I would say:
Jan - 1st batch of MMC Special Days
March - Month of Hope, on the doorstep to Spooky Spring / Halfoween
May - "The Road" has opened up - 2nd half of the year and Autumn, Leon Day, just around the corner.
I'd be interested in hearing yours.
I will say JOL days are my favorite special day of the three. I love them all but there is something I like a little bit more.
The JOL days leading up to Spooky Spring then leading to Halfoween really get me thru the first part of the year.
