More sweepstakes end on the last day of the year than on any other day of the year. Because so very many sweepstakes are coming to a close on the same day, it's a good idea to go through them all to make sure you haven't overlooked any that you want to win.
Note that as new sweepstakes that end on December 31, 2014 are added, they will be placed at the end of the list. So be sure to continue to the end of the last page to check if you have missed any newly-added sweepstakes.
