How Long Is It Acceptable for People to Leave Their Christmas Decorations Up After the Holidays?

My family has always loved Christmas.  Particularly my Mom, she didn't quite go nuts, but ti was close.  But right after New Year's, we always take down our Christmas stuff, the lights, everything.It's not that we don't want to keep the decorations up, but since the holiday is over, it seems pointless.

But every year I see people who leave their decorations up for weeks . . . or sometimes months . . . after Christmas is over.

Why do people leave their decorations up for so long?  I know some Eastern Orthodox Christian churches celebrate Christmas on January 7th . . . because they use a different calendar . . . but I'm not sure that's it.

Is it because people don't want the holiday season to end . . . they like the way the decorations look . . . or is it because they're just lazy?

How long after Christmas is over is it acceptable for people to leave their decorations up?

Let me know what you think about it!

Christmasly yours,
