Why Christmas in july

A couple years ago, during one of our family Christmas get togethers, I mentioned to everyone we should do our Christmas in July.  My reasoning was to cut down on family members not being able to travel due to bad weather.  Also, as our individual families are expanding, it would open up more time to enjoy the holidays with them versus struggling to find a day that works with Mom, Siblings, Kids, Grandkids, Nieces, Nephews, Cousins,  various in-laws, etc...  

Well, I was met with scoffs, no ways, why's, you're insane along with some other Christmas family niceties. So, no Christmas in July for us. However, this did lead me to wondering why/how Christmas in July got started.  
There seem to be numerous reasons why or how Christmas in July got started.  Some say it's because of the different seasons between the North and South Hemisphere.  Others say it has to do with breaking up the year to allow for more gift giving and partying, an excuse for a joyous family gathering.

​In the United States, the earliest mention of Christmas in July was in North Carolina at a girls summer camp.  They threw a festive party complete with a Christmas tree, gifts and Santa Claus in 1933.  In 1940, the term gained national recognition with the release of the movie, Christmas in July.  The movie, however, was about a man who won a contest and bought gifts for family members and friends.  Through out the 40's various organizations used it as a marketing ploy, The USPS, Military and Chruches.  In the 50's more American retailers started using Christmas in July for summertime sales.  

Australia has a Christmas in July which is known as Yulefest or Yuletide.  This does not replace the  December 25th Christmas and it is not celebrated by everyone. It also isn't a holiday.  July is the coldest winter month, so it emulates the Christmas holiday in the Northern Hemisphere.  Popular Christmas in July themed fuctions, and ticketed events are popular during this time.  
Regardless if people can agree on the origins of Christmas in July, it has become a marketing ploy here in the United States and other Countries.  Christmas in July is synonymous with SALE!!  

Let me know what you think of Christmas in July!  Do you celebrate with Christmas tree and gifts?  Santa Claus?
