ReGiftmas or Re-Giftmas is an annual holiday season, typically celebrated from the first Monday following Christmas until January 31. As a Moveable Feast, the exact date varies based on tidal calculations, the Leap Year, and discrepancies between the Julian and Gregorian Calendars. The holiday is marked by the sale, recycling or “re-gifting” of unwanted gifts, usually received during the Christmas holiday. Commonly regifted items include sweaters, branded items from Sharper Image, and Claxton fruitcakes. While the practice of regifting is not unknown during other seasons, it reaches its zenith during the post-Christmas glut of unwanted gift items.

ReGiftmas is related by proximity to the more familiar Christian holiday, but the celebration of ReGiftmas is typically celebrated in a spirit of unadorned self-interest. Some celebrants have attempted to turn the holiday into an altruistic celebration and an opportunity to extend the spirit of generosity into the new year. However, one popular song illustrates the most common tone of the festivities: “No More Stupid Stocking Stuffers / No More Frozen Fruitcakes / I’m Getting What I Want This Time / I’ll Sell This Ugly Sweater if That’s What it Takes.”
