colloquialtime

How it's used

Adding 正 after a time expression emphasizes that the time is precise and not a minute earlier or later. It functions similarly to the English word sharp. While it can be used for any hour, it is most frequently heard when coordinating meeting times or deadlines to avoid ambiguity.

Examples

We will wait at the entrance at exactly one o'clock.
Is the meeting starting at exactly one o'clock?

Common phrases

one o'clock sharp

Common mistake

Do not confuse this with 一點鐘, which simply means one o'clock. Using 正 implies a strict, punctual requirement that is not present in the neutral term.
