Hunt back in the archives a couple days...
The long count rollover isn't solstice linked.. it's just a sequential
day count (think TAI)..that happens to roll over on the same "day" as
the solstice occurs.. and it only ticks in "days"..
The Mayans had a solar calendar too.. that one is solstice linked.
And just as with discussions in modern times about leap seconds and UTC
vs TAI, there were political factors at work with respect to the two
calendars..

plus ça change, plus c'est la même chose
