"At the striking of the hour" refers to the specific moment when a clock or other timekeeping device signals the start of a new hour by producing a distinct sound or other recognizable marker. This phrase is often used to indicate the precise time when a particular event or activity is scheduled to occur.
In a literal sense, it implies that an action or arrangement should take place immediately after the clock strikes a whole number of hours—such as one o'clock, two o'clock, etc.—as marked audibly by the sound of a bell, chime, or clock mechanism. This can be seen in traditional contexts such as announcements on public transportation schedules, punctuality in formal appointments, or specific timed activities.
Figuratively, "at the striking of the hour" can connote a sense of punctuality, exactness, or synchronization. It emphasizes timeliness and the expectation of promptness, particularly when used to convey the importance of meeting deadlines, adhering to a strict timetable, or acting in a synchronized manner.
Overall, "at the striking of the hour" incorporates the concept of a definitive and audible timestamp, often associated with the hourly chime of a clock, to signify the specific point in time when an action, event, or arrangement should occur.
