Skaters must be older than 13 and less than 19 (or less than 21 for male pair skaters and ice dancers) by 1 July of the previous year. For example, to compete at the 2010 Junior Worlds, skaters had to be at least 13 and younger than 19 (or 21) by 1 July 2009. A skater must turn 13 before 1 July in their place of birth, e.g. Adelina Sotnikova was born a few hours into 1 July 1996 in Moscow and was not eligible to compete at the 2010 event.
