why do hispanic cultures celebrate christmas on the 24th

Christmas is celebrated on different days in different cultures and religions. In some Hispanic cultures, such as Mexico, Argentina, and Cuba, it is traditional to celebrate Christmas on December 24th, or Noche Buena, which means "good night" in Spanish. This tradition comes from the pre-Christian solstice celebrations that took place during the winter solstice. In these cultures, the celebration on December 24th is often the main celebration, with the focus being on spending time with family, sharing meals, and exchanging gifts.
