Christmas break is typically two weeks long, and it usually ends on the first day of the new year. So, if you were on Christmas break right now, it would end on January 1st. However, the exact length and timing of the break can vary depending on where you live and the type of school you attend. Some schools may have a longer or shorter break, or they may have a different schedule altogether. But generally speaking, most schools have a two-week break for Christmas.
