In Japan, transportation schedules are usually given using the 24-hour clock. For example, 1:28 p.m. is expressed as 13:28. In the dialogue below, both speakers are waiting for a train scheduled to arrive at 13:28.
Japan has a modern and highly developed public transportation network. Japan Railways, commonly known as JR (ジェーアール), was once the country’s largest public corporation. It has since been privatized and divided into several regional companies, each of which still uses the “JR” name. Trains operate on extremely tight schedules and are known for their remarkable punctuality. In major cities, commuter trains during the morning and evening rush hours are often very crowded. For new passengers, learning to navigate these conditions is simply part of everyday life in Japan.

Japanese doesn't have an expression equivalent to "half an hour." Instead, we just say ３０分. 半時間（はんじかん） is understood, but it sounds bookish and unnatural.
