How it's used
Refers strictly to the day two days prior to the current one. Unlike formal written Chinese, it is used naturally in casual speech to pinpoint specific past events without needing to specify a date. It functions as a time adverbial and does not require a preposition like 喺 before it.
Examples
We went hiking the day before yesterday, it was so tiring.

Common phrases

the night of the day before yesterday
Common mistake
Do not confuse this with 大前日, which refers to three days ago. Learners sometimes mistakenly use 兩日前, which is grammatically understandable but sounds less natural than the specific term 前日.
