... the new calendar according to Sam, which starts the pre-feast of the Nativity on Labor Day in September.
Labor Day is of course a movable holiday in the Fiscal cycle. That Fiscalion has an accumulating bias, and the pre-season that used to started the day after Thanksgiving has now, unfortunately, deteriorated to beginning even on Labor day as noted.
One must properly consider the calendar and its effects. There are no differences between the Gregorian Calendar and the Julian Calendar, save those pesky 13 days. The Feast of the Great Pumpkin has one pre-festive day and the usual octave of post-festive days. The problem comes with the Revised Gregorian Calendar (which is called "Sam's Calendar" in some parts of the country). It has determined that you can't rush into a feast of this rank without an extended pre-feast. But is also has been determined that there are no post-festive days at all because the pre-festive periods of Thanksgiving and the Christmas out rank the post-festive days of Pumpkin and therefore suppress it.
The Revised Gregorian Calendar (aka the "Revised New Calendar" and "Sam's Calendar") now prescribes:
Labor Day until the Feast of the Great Pumpkin:
--Pre-Festive Days of the Great Pumpkin
--Pre-Pre-Festive Days of Thanksgiving
--Pre-Pre-Pre-Festive Days of Christmas
--Feast of the Great Pumpkin
November 1 through the Wednesday Before the Fourth Thursday of November:
--Pre-Festive Days of Thanksgivng
--Pre-Pre-Festive Days of Christmas
Forth Thursday of November
Thanksgiving Day through November 30
--Pre-Festive Days of Christmas
--Post-Festive Days of Christmas (aka "Throw Out the Tree Week")
--College Bowl Day and New Year's Day
Now there is some confusion among those following the Julian Calendar about the date of Thanksgiving Day. Some follow the traditional Julian Calendar and place Thanksgiving Day on the 4th Thursday of "Julian" November (this year it would fall on Gregorian December 9th). This, of course, plays havoc with the pre and post-festive periods (are they calculated using the traditional Julian Calendar or the New Revised Gregorian Calendar). And there are those who celebrate according to both calendars.
Now that I've written all that I hope it is clear. If not, please ask Neil to pass you the bottle of Wild Turkey (yes, it is the customary drink for Thanksgiving Day but I'm sure no one will care if we start the pre-festive toasts a bit early).
