Due to ongoing COVID-19 pandemic in Turkey, the regular season, which is used to start in the Fall and to conclude in the next year's Spring, was postponed to Spring with changed competition format. The 2020–21 season starts on 17 April and ends on 5 May. The number of participating teams increased to 16, including all the 12 teams from the 2019-20 First League season and additional 4 top teams promoted from the 2019-20 Second League season.[3] The 16 teams are divided in four groups of four teams. Each of the four promoted Second-League teams are assigned to one group. Each team in a group plays three matches in total. The first two top teams of each group are qualified for quarterfinals in a single-elimination tournament. The team winning the final match will represent Turkey at the 2021–22 UEFA Women's Champions League .[3]
