Allen's Interval Algebra

Allen's Interval Algebra is a way to describe how time intervals relate to each other. It defines 13 possible relationships, such as one event happening before, after, during, or overlapping with another. For example, if one meeting ends before another starts, they are "disjoint." If they overlap, they occur simultaneously for some time. This system helps in tasks like scheduling, temporal reasoning, and understanding sequences of events by providing precise language to compare how intervals relate in time.
