Since Guam has palm tree upon it, it can easily be turned into a holiday themed flag. In this case, white lights are added. It is also night time.
Although a world away Guam is that other extra part of the United States like Washington DC and Puerto Rico that does not get a star on the national flag.
Christmas is celebrated in similar fashion to the mainland, with added Guamanian dishes, minus the snow and ice.
Christmas in California can vary. Up north you have the Germanic Christmas with snow and darkness, but down south you have a Holy Land style kind of weather. Because Southern Cal is at the same latitude of Israel, thus Mary and Jo would most likely feel at home in San Diego, rather than say Sacramento on December 25th.
In any case, the California flag with a Christmas theme has the bear in a Santa outfit, minus the boots. The bear is walking on snow covered ground and it is snowing. Finally the word 'Republic' is replaced with 'Christmas.'
Since the fraternal partner of California is Columbia: District of Washington, the flag of DC too has a Christmas theme. For DC the upper stripe is green and so is the middle star. It also has 'Merry Christmas' written in the stripes. The upper green stripe has it in red, while the lower stripe has it in green with matching coloured balls.
Several flags appear in the True to Life Nightmare Before Chirstmas...Universal's Krampus 2015. In the opening sequence plastic red holiday pennant flags can be seen at the entranceway. The store is obviously having a Christmas blowout sale, and the shoppers are show a corrupted spirit of Christmas. It seems contagious as the staff, children, and older folks act in ugly and greedy fashions. There is no famine, no natural disaster, no war threat, yet, their avarice and selfish spirit is a common place behavior during the American holiday season.
The US flag makes a brief cameo in Universal's Krampus 2016. During the introductory scene the
US flag appears as a badge on the security store staff at the fictional Mucho Mart. The flag is on the left shoulder of the security agents who have fired their tasers.
The UK flag also makes a small appearance in Krampus as a bedroom decoration for the more than cool for family teenage daughter. It is just barely lit in the background.
Krampus 2015 is the key note film that captures the feels and style of the 20-teens. Cell phones, aggressive shoppers, and ghoulish bystanders who record heinous acts for joy as voyeuristic scandal-standers.
Grumpy Cat became more than a meme, a kind of institution in her own right. In the movie Grumpy Cat's Worst Christmas Ever several flag make an appearance. The US stars and stripes appear as a vest for the supporting heroine of the Lifetime movie.
The Grumpy Cat Christmas Special is light farce, something of a cartoon with silly antics for the whole family. Grumpy steals the show. It is packed with that spirit of the 20-tweens, wry and dry internet humor galore. If you are a fan of Grumpy Cat, this is a cheesy delight for people who love cats.
Another vexilloid of interest are the frozen blue plastic pennants at Santa's Village. You can just barely make them out on top of the candy cane towers on either side of Santa. Santa at the mall is a staple in most subruban American communities. Beforehand, Santa used to appear at larger general stores.
Another unique logo to appear in this movie is the 'Louieton Animal Rescue' seal. It features a dog and a cat and typical circular seal.
There are several Christmas Islands! Perhaps the most famous is the one next to Indonesia that is populated mostly by Chinese Australians. There is a Christmas island in Canada, Nova Scotia. Tasmania even has two Christmas Islands. But a close runner up to equatorial Christmas Island of Australia is Christmas Island of Kiribati.
The flag for Kiritimati— Christmas Island of the North — is loosely based upon the flag of Christmas Island of Australia. However there are several differences. First, the central disc has the outline of Kiritimati. In the bottom half, the national bird of the Kiribati is flying in the lower red half, which is the frigate bird. On the upper blue half is the 'Northern Cross Constellation' which is within the constellation of Cygnus. Additionally a seven pointed star near the fly represents the star Vega, which was made popular in movie Contact 1997.
The islanded nation of Kiribati is a geographic wonderland, since it sits at the cross hairs of geography. Kiribati straddles the equator and 180th Meridian, which is the opposite of the Prime Meridian. Likewise the island of Kiritimati translates to Christmas Island. Many older maps retain this name.
Like Aussie Christmas Island, Central Pacific Christmas Island was a British Colony. During the War of Endless Tears both Christmas Islands were occupied by the Imperial Japanese Navy. Eventually, the UK regained control of the Kiribati and gave it independence in 1978. Then in 1983 the US released its claim to several of its islands.
Interesting aspect about Christmas Island of the North is that it has cities names Poland, Paris, London and every one's favorite name for a city... Banana.
Everyone knows about Australia's Christmas Island. But did you know that Canada also has a Christmas Island? And this island is more a kin to what most of us think about Christmas in Europe and North America, a kind to what Santa would expect in at the North Pole.
The Christmas Island flag has a Canadian pale with two crossed candy canes. Three green maple leaves sit at different angles. This flags is themed to say Canada and Christmas at the same time.
Christmas Island, Nova Scotia is and island on and island of sorts; since it is on Cape Breton Island.
The funny thing about Christmas Island, is that its flag is not so Christmassy. So in honor of Christmas this flag named after Christmas deserves the Northpolarization treatment. Red and green lights are added around the border, a Santa hat is on the bird, and the Southern Cross stars have a warm glow. Now, this Christmas Island flag says Christmas!
