Winterval was a festival that used to happen in a place called Waterford in Ireland. It was a time when people would come together to celebrate the winter season and have fun with their families and friends. They would do lots of things like watching parades, going to Christmas markets, and listening to music.
But sometimes people would get confused about what Winterval was all about. Some people thought it was only about Christmas, which is a holiday that some people celebrate in December. Other people thought it was about lots of different celebrations that happen at the same time, like Hanukkah or Kwanzaa.
So some people decided that they wanted to change the name of the festival so that everyone would understand that it was for everybody, not just for one group of people. They chose a new name, but some people still call it by the old name.
In the end, what's really important is that Winterval (or whatever you want to call it) is a time for people to come together, be happy, and enjoy the winter season.
