Small real tree with lights goes outside the front door on 1st Dec.
Indoor tree will be 6th Dec this year, earlier than usual because family coming to stay on the 7th.
Other decs., wreath on door, same time.
Christmas cards are blutacked to painted surfaces as they arrive.
Nothing comes down until 6th Jan - January is dreary enough anyway - though might be 5th this time since youngest Gdc’s birthday is the 6th.
