Around the clock
The idiom “Around the clock” is used to describe something that is done continuously or without stopping, 24 hours a day, 7 days a week. It implies that an activity or process is ongoing non-stop, without any breaks or interruptions. The phrase originates from the idea of a clock with its hands moving continuously around the face, indicating the passage of time without pause.
When someone says they are working “around the clock,” it means they are working tirelessly and without rest to accomplish a task or meet a deadline. This idiom is commonly used in contexts where there is a need for constant attention or effort, emphasizing the continuous nature of the action being described. For example, a hospital emergency room operates around the clock to provide medical care at all times. Similarly, customer support services may run around the clock to assist customers whenever they need help, regardless of the time of day.
