Is there a U23 European Youth Championship in Europe? Is there a U23 in the World Youth Championship? Why is the age group set at odd numbers (such as U 17, U 19) instead of even numbers?

Take the ongoing World Youth Championship as an example. It was born after the U20 World Youth Championship, that is, 199 1 1. These players participated in the youth championships on all continents, which were also qualifiers for the World Youth Championship. The World Youth Championship was held one year before the World Youth Championship, that is, U 19. Some time ago, the World Youth Championship was called U 17 World Youth Championship.

Europe has the U23 European Youth Championship as a qualifier for the Olympic Games. Because Europe and Asia are different, there are no Olympic qualifiers, and the semi-finals of the European Youth Olympic Games directly participate in the Olympic Games, but there is no U23 in the World Youth Championship. Therefore, there are odd and even, because there are people who appear on the world stage as the main force in every era, and they all have opportunities to show.
