Thanksgiving

I just learned that Thanksgiving dates are different between Canada and the US.
It originated from Indigenous harvest festival.
Since Canada is farther north, the harvest season is earlier.
Therefore, Thanksgiving is celebrated on the second Monday of October in Canada,
and on the fourth Thursday of November in the US.
