I do not know the chronology of any of these except the obvious ones, but I do recall that stump winter is when all the burning wood is gone and you have to go bust up the stumps to burn for wood. My inclination is that this would be very deep into spring because you cannot chop down any more trees because they are already greening up - so you burn the stump wood. Linen britches is supposed to be when you have already put away your winter wardrobe and it turns cold again, so you have to drag your linen britches back out. Not sure how accurate any of this is. - Leshia Fair
