Christmas lawyer wins settlement against HOA that tried to shut down his holiday display in Idaho, plans bigger celebration this year with their settlement money.

Since the early 20th century, Christmas has evolved from a religious holiday to a hugely popular cultural holiday observed by Christian and secular people across the globe who gather with families, exchange gifts and cards and decorate Christmas trees. Here’s a look at the history, beliefs and the evolution of Christmas:

Post offices will be open and delivering mail on Christmas Eve, despite an executive order declaring it a federal holiday. UPS and FedEx will both be making deliveries on Christmas Eve, though some services may be modified or require prearrangement. Most banks will be open on Christmas Eve, but many will operate with shortened or adjusted hours.

The history of the White House Christmas card list is long, unique, with annual messages as unique as the former presidents themselves.

The U.S. Postal Service is set to open on Christmas Eve and December 26 despite an executive order from President Donald Trump.

What actually constitutes a white Christmas depends on where you’re celebrating. In the United States, the National Weather Service sets a bar: at least one inch of snow must be on the ground on Christmas morning, or at least one inch must fall during the day. To the north, Canadians have a slightly different measure.

If you're hoping for a festive skywatching surprise, Christmas week is shaping up to be more active than usual in space. Fast solar wind from a large coronal hole on the sun has already triggered minor (G1) geomagnetic storms and forecasters say unsettled conditions could persist into Christmas.

Del Frisco’s restaurants will be open for business on the holiday. Many Denny’s restaurants will be open on Christmas. Eddie Merlot’s restaurants will be open on the holiday. Select El Pollo Loco locations will be open on Christmas. Customers can view the full list on the chain's website.
