How did this festival originate?

The precise beginnings of the Christmas in July tradition is not very clear, although it is commonly believed that it actually started in Europe, as a way to celebrate Christmas in summer. During the summer months in the northern hemisphere, the weather becomes increasingly warm and many people crave the coolness of winter. Amid the scorching summer months, people miss the gift-giving, and holiday spirit of Christmas time. Though it is not known when it started exactly, it is probably from the 80s that the festival began to be celebrated. The earliest Christmas celebrations in July saw people throwing parties that imitate the actual Christmas festivities in December. The celebrations also included other Christmas traditions like Santa Claus, ice cream and other cold foods, and gifts. It was held that celebrating in the warm season would ensure a strong, happy winter Christmas season.
