In Longfellow's Evangeline: A Tale of Acadie, during what part of the year/holiday season is Evangeline exiled from her home? Some details seem to imply Halloween and others Christmas.
In the poem itself, there are several hints that point me to a specific answer (my emphasis). According to the Prelude, it is probably in October:
Waste are those pleasant farms, and the farmers forever departed!
Scattered like dust and leaves, when the mighty blasts of October
Seize them, and whirl them aloft, and sprinkle them far o'er the ocean
Naught but tradition remains of the beautiful village of Grand-Pré.
In Canto II, we find that the harvest has apparently just passed and,
Such was the advent of autumn. Then followed that beautiful season,
Called by the pious Acadian peasants the Summer of All-Saints!
The "Summer of All-Saints" seems to allude to both the Celtic new year (Samhain, "Summer's End") as well as All Saints' Day, leading to a conclusion that the expulsion takes place around Halloween. Despite this, not much later in Canto II, we find that,
Fragments of song the old man sang, and carols of Christmas,
It is very odd that all of these hints seem to point to Halloween yet someone is singing Christmas carols. Christmas is definitely not in October and, at least in North America, takes place a month and a half to two months after the completion of the harvest and definitely not contemporary to it. In addition, North American winter traditionally starts at the winter solstice (a few days before Christmas), firmly making Christmas a winter holiday and Halloween a fall/autumn one.
When in the year is the village of Grand-Pré burned and Evangeline and Gabriel exiled? Is it around Allhallowtide, Christmastide, or some other season of the year?
