The World and most Protestants:
Christmas: 24 hours max on the Dec 25th. The tree is out on the 26th.
Easter 3 to 6 hours max, taking account of Church, Easter brunch, maybe an Easter dinner.
Anglican: we celebrate seasons not days
Christmas: 12 days from Christmas day to Epiphany. I leave the tree up to sometime after Epiphany.
Easter : 50 days from Easter Sunday to Pentecost.
