A football match typically consists of two halves of 45 minutes each, resulting in a total of 90 minutes of playing time. However, it’s important to note that there is usually additional time added at the end of each half to make up for stoppages in play, such as injuries or substitutions. This added time is known as stoppage or injury time, and it can vary from a few minutes to several minutes depending on the circumstances of the match. Therefore, the actual duration of a football match can be slightly longer than 90 minutes.
