I never did understand why canada and usa have this holiday a month apart
I think it has something to do with our seasons and the harvest... because the further north you are, the shorter the growing season, so since thanksgiving is supposed to be a celebration of the end of the harvest, it coincides with the regional end of harvest season (though in the US because the climat is so polarized, I guess they just picked a date in the middle, since the growing season never ends in California)
