Depends on the sport. U21 football, for example, has at times historically had people remain eligible until the end of the season in which they've turned 21.RedheadDane said:Libertine Seguros said:Cadets is U16 or U17 depending on how you classify it. As neither Niewiadoma nor Ludwig got to defend their U23 WWT jerseys despite being 22 for the vast majority of the season they defended it, you'd define it as U17, as you become ineligible in the year you turn 17.
Isn't that how it's always counted. You're too old for - say, U17 - the year you turn 17, no matter if your birthday is January 1, or December 31.
