What is the term used to describe the time that is 30 minutes past the hour?

The term that describes the time which is 30 minutes past the hour is "half past." This terminology comes from the way we tell time using the hour and minute hands on a clock. Specifically, when the minute hand is pointing at the 6, it indicates that it is half of an hour past the preceding hour. For example, if the hour hand is on 2 and the minute hand is on 6, it is said to be "half past 2." Understanding time in this way is foundational in telling time, as it helps to visualize the passage of minutes in relation to whole hours. Other options, while they describe different time intervals, do not accurately represent the 30-minute mark.
