How it's used
Focuses on the continuous or relentless nature of an action rather than just the passage of time. It often carries a sense of exhaustion or extreme dedication when describing work or effort. Unlike formal Mandarin expressions, it feels very natural in casual speech when complaining about a busy schedule.
Examples
They are working day and night.

Common mistake
Avoid using it to mean a specific 24 hour period or a calendar day. It describes the duration of an activity rather than a unit of time.
