How it's used
While 晝夜 is understood in spoken Cantonese, it carries a slightly formal or literary tone compared to the more common 日頭夜晚. It is frequently used in idioms or set phrases to describe continuous, relentless action. You will often hear it used to emphasize the duration of a task or a persistent state of mind.
Examples
They work day and night without stopping, it is really exhausting.

Common mistake
Avoid using 晝夜 in casual, everyday conversation when referring to simple timeframes, as it can sound overly dramatic or like a written text. Use 日頭夜晚 instead for natural speech.
