Weird. These are really popular with Catholic people in Canada. They are found in Catholic Churches, schools and usually the center of dinner tables during Advent. It's always an evergreen wreath with 3 purple candles, 1 pink candle and 1 center candle which is unusually white. The wreaths at church get lit at Sunday Mass, one candle for each week of Advent then the center one on Christmas. Generally wreaths at dinner tables are the same but you will light them at Sunday dinner (I can't remember if they get lit throughout the week as well and you just light the same number of candles as the same week of Advent)

I know people who aren't religious or no longer are, sometimes still use a wreath without candles as a centerpiece for their dinner table in the winter. It just provides a nice Christmas feel, similar to a door wreath
