Christmas has been celebrated in the United States since the country's earliest days. The first recorded celebration of Christmas in America took place in 1639 in the Massachusetts Bay Colony. However, the holiday was not widely celebrated or observed until the early 19th century when it became more popular due to the influence of German immigrants. It wasn't until the mid-19th century that Christmas became a national holiday in America and gained widespread popularity. Since then, it has become one of the most important and beloved holidays in the country.
