Hey, madleinx!
For reasons that I can't explain, "midsummer," or Litha in my case, occurs on the first day of summer. Now, why they put the middle first is beyond me, but since this whole thing has been going on for millennia, there's no longer anyone around to ask.
I have to admit, I'd also get behind a holiday that has a man baking bread...or anything else for that matter!
(I'd like to request that all male bakers reading this board please not take offense.
)
