November 3rdIt's Mandarin day.
Everyone's hands turn all yellow when we show them to each other afterward.
December 3rd is also Mandarin day.
Culture Day (Bunka no Hi) on November 3 is originally the holiday dedicated to the Emperor Meiji, whose birthday according to the Lunar Calendar fell around this date. Before the war, people would gather at shrines throughout the country and bow in the direction of the Imperial Palace. Under the postwar constitution the day was rechristened as "Culture Day", as after all autumn is a time for cultural pursuits.
On November 3 the Emperor awards the Order of Culture to people of outstanding achievement in the fields of science, art or culture. The Emperor presents the awards (shaped as a mandarin orange blossom with purple cord; the mandarin orange was planted in the palace courtyard since Heian times and symbolizes eternity - in this way the timelessness of culture is expressed) during a ceremony held in the palace.
