Time-frame: The tournament was held at Khanty-Mansiysk, Russia from September 22nd until October 3rd.
Much like some of the earliest youth championship events (for example, see 1995 WYCC(1) sections whose sections were held at either São Lourenço or Guarapuava in Brazil), the dates and cities of the tournament locales were split again during this series for the event bids.
Other similar youth championships are detailed below:
World Cadets U12 (2016) (open and women's Cadet's sections, held at Batumi, Georgia 18 - 31 October 2016) and World Youth Championship U18 (2016) (open sections of WYCC, some games including U14, U16 and U18) - held at Khanty-Mansiysk, Russia from September 22nd until October 3rd.
World Junior Championship (2016) and World Junior Championship (Girls) (2016) (both were at KIIT University at Bhubaneswar from August 7th until the 22nd)
