This season's Champions League and Europa League competitions will be completed in August with 'final eight' tournaments in Lisbon, Portugal and in cities across Germany, reports BBC Sport.
The Women's Champions League will also be a knockout tournament, in northern Spain between 21 to 30 August.
Competitions were suspended in March because of the Covid-19 pandemic.
Uefa also confirmed that all 12 original host cities will stage matches in the delayed Euro 2020 finals.
That competition will now start on 11 June 2021. The outstanding play-off matches will be staged during the international windows starting on 8 October and 12 November, respectively.
