Once upon a time, Christmas celebrations wouldn’t have been anything without caroling, and this is exactly what is celebrated on Go Caroling Day on December 20. It’s about nothing else but merrily singing songs from door to door in the spirit of the holiday season. Christmas carols were very popular decades ago, before there was digital entertainment to distract us. As it became more and more uncommon to sing along to carols, Go Caroling Day revives and preserves this classic tradition.
