Personally, I don't find it odd at all. I've given and received ornaments for Christmas many times.
And in my house, Christmas decorations don't come down until New Year's day. So there's at least 7 days to enjoy it.
Not to mention that there's always something left out that doesn't get put away.
Technically, there are really 12 days of Christmas. Christmas doesn't really end until Epiphany.
The Twelve Days of Christmas is probably the most misunderstood part of the church year among Christians who are not part of liturgical church traditions. Contrary to much popular belief, these are not the twelve days before Christmas, but in most of the Western Church are the twelve days from Christmas until the beginning of Epiphany (January 6th; the 12 days count from December 25th until January 5th). In some traditions, the first day of Christmas begins on the evening of December 25th but the following day is considered the First Day of Christmas (December 26th).
The origin of the Twelve Days is complicated, and is related to differences in calendars, church traditions, and ways to observe this holy day in various cultures. In the Western church, Epiphany is usually celebrated as the time the Wise Men or Magi arrived to present gifts to the young Jesus. Traditionally there were three Magi, probably from the fact of three gifts, even though the biblical narrative never says how many Magi came. In some cultures, especially Hispanic and Latin American culture, January 6th is observed as Three Kings Day, or simply the Day of the Kings. Even though December 25th is celebrated as Christmas in these cultures, January 6th is often the day for giving gifts. In some places it is traditional to give Christmas gifts for each of the Twelve Days of Christmas. Since Eastern Orthodox traditions use a different religious calendar, they celebrate Christmas on January 7th and observe Epiphany or Theophany on January 19th.
So, Technically, It's ok to have decorations up until the 19th of January.
