How it's used

Focuses on the duration of an activity extending from night until dawn. It is frequently used as a verb phrase, often paired with verbs like 溫書, 趕工, or 打機 to describe staying awake for a specific purpose. Unlike the more formal 徹夜, this term feels natural in casual conversation when describing a long, tiring night.

Common mistake

Do not confuse this with 熬夜, which emphasizes the act of staying up late rather than the duration of the entire night. While 熬夜 can be used for staying up until 2 or 3 AM, 通宵 strictly implies staying awake until the sun comes up.
