New Year's day occurs every January 1rst. It celebrates the coming of a new year to Spain.
Traditionally celebrated with lots of blasting fireworks and sparklers, this holiday is a joyful one. Many people get the day off since it is a national one.
This holiday started way back in Roman times, but was changed to January 1rst with the change in a more accurate calendar. It was always debated when the new year should officially start, but the 1rst of January seemed like the right fit.
