Playing games with an official event

From winter time, to summer and now back to winter...but for how long? This is not a story of some bears who hibernates in their holes at cold days / nights who wants to walk and enjoy without any interruption in the hot weather, however, this is a true tale from a football competition.
Many times the Africa Cup of Nations was held in the first 2 months on every two years, in 2019 it was moved to a new season in June / July, while two years later the tournament is going to be played to its recognizable schedule. Last Wednesday it is officially confirmed (with the request of the host country) that this event is going to be shifted again to the original layout from 09 January until 06 February 2021 because of the unfavorable rainy conditions in Cameroon at summer time.
