Definition

The day before yesterday; two days ago.

colloquialtime

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.
Did you go to see him the day before yesterday?

Common phrases

the morning of the day before yesterday
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.
