a.
Mass-consumerism day
b. The day before
Boxing Week
c. Christian holiday celebrating the birth of
Jesus of Nazereth which is now belived to have occured in
May. The reason for this discrepency is probably that the christians assimilated the old celebration of the
Winter Solstice (traditionaly held 4-5 days after the actual
solstice due to imprisistion in measureing systems (
megaliths like
Stonehenge are not able to demonstrate that the solstice has occured until a few days after the event)).
