Unholy mess over Advent
I am afraid that Advent is not "the time between All Saints Day on November 30 and Christmas Day". All Saints Day is November 1 and, contrary to the belief of Advent calendar manufacturers, Advent starts four Sundays before Christmas. For penance, as an added mathematical exercise, you can investigate whether that is always the first Sunday in December.
