Christmas is almost here, and if you need to run out to grab a last-minute ingredient for your gathering, you'll have some options on Christmas Day.

Some of the country's biggest supermarket chains and department stores have limited hours on Christmas Eve, and most are closed on Christmas Day.

If you need more eggnog or ingredients for another batch of Christmas cookies, watch the clock today. Why it matters: Most grocery stores close earlier than usual for Christmas Eve and many will stay closed on Christmas Day.
