Hello Codeforces! Next June will take place the OII 2025.
The Ibero-American Olympiad in Informatics (OII) is an annual programming contest for young students enrolled in a high school from Ibero-American countries. Students compete on an individual basis, with up to fifteen students competing from each participating country. The competition has only one round, which happens around June-July each year, and is done online.
