The European Championship, commonly referred to as the UEFA European Championship or simply Euro, typically lasts for about a month. The tournament starts with the group stage, where 24 teams are divided into six groups of four teams each. The top two teams from each group, along with the best four thirdplaced teams, advance to the knockout stage, which includes the Round of 16, quarterfinals, semifinals, and the final. Overall, the tournament usually spans over 31 days from the opening match to the final.

The duration of the European Championship may vary slightly depending on the tournament schedule and any potential changes to the format.
