IOI 2017 Date and Location

The IOI 2017 will take place during July 28 – August 4, 2017 in Tehran, the capital of Iran. Please mark your calendars!

The earlier announced date, July 21-28, 2017, had a 3-day overlap with the International Mathematics Olympiad (IMO 2017). Hence the IOI 2017 organizers decided to start the event one week later to resolve this issue.
