The calendar and kick-off times from the play-offs onwards are established by the UEFA administration.
The play-offs, group matches (subject to), round of 16 matches, quarter-finals, semi-finals and final kick off at 21.00CET. Exceptions to this rule can be set by the UEFA administration.
Each matchday in the group stage, two of the Tuesday matches and two of the Wednesday matches kick off at 18.55CET. Exceptions to this rule can be made by the UEFA administration.
The fixtures within a group on the last matchday are played simultaneously.
In principle, a club must play all its matches in the competition at one and the same venue. As of the play-offs the venue can be changed only based on a UEFA decision. A venue may be the ground of the home club or another ground in the same or another city within the territory of its association. Exceptionally the UEFA administration may accept a venue in the territory of another UEFA member association if no other suitable venue is available on the home territory. In principle, match venues are approved only if direct international flights and/or charter flights are able to land within an acceptable distance of the venue, in the country of the club concerned. All match venues are subject to the approval of the UEFA administration.
If, at any time during the season, the UEFA administration deems that, for whatever reason, a venue may not be fit for staging a match, UEFA may consult the association and club concerned and ask them to propose an alternative venue, in accordance with the UEFA requirements. Should such an association and club not be able to propose an acceptable alternative venue by the deadline set by the UEFA administration, UEFA may select an alternative, neutral venue. The club concerned will have to make all the necessary arrangements for the staging of the match together with the relevant association and local authorities. In both cases, the costs of staging the match are borne by the home club. The UEFA administration takes a final decision on alternative match venues in due time.
The date and venue of the final are chosen by the Executive Committee.
