In the European Championship, a standard football match consists of two halves, each lasting 45 minutes, with a 15-minute halftime break in between. Therefore, the total duration of a European Championship match is 90 minutes.
However, it is important to note that the actual time taken to complete a match may be longer than 90 minutes due to stoppages for injuries, substitutions, time-wasting tactics, and added time at the end of each half. The referee has the discretion to add additional time at the end of each half, known as "injury time" or "stoppage time," to compensate for any time lost during the game.
Therefore, while the standard duration of a European Championship match is 90 minutes, the actual time taken to complete a match may vary depending on the circumstances during the game.
