Thirty minutes, often written as 30 min or 30min, is a unit of time equal to half an hour. It comprises 1,800 seconds and is equal to 0.5 hours on the decimal scale. In digital timing, 30 minutes is represented as 00:30 in a 24-hour clock or as a duration of half an hour.

In daily life, 30-minute blocks are commonly used for scheduling appointments, meetings, or tasks. They provide a concise period long enough for a brief discussion, a focused activity, or a single event, while allowing multiple items to be arranged within a single session.
