Para se perguntar as horas em inglês, temos algumas expressões:
- What time is it? (Que horas são?) – Mais usada
- What’s the time? (Que horas são?)

It’s five o’clock. (São cinco horas).
It’s midday. (É meio dia).
It’s midnight. (É meia-noite).

- Quando dizemos as horas exatas (sem os minutos), acrescentamos a expressão o’clock.
Nesta expressão o’clock, este o’ é contração de of the: It’s five o’clock = It’s five of the clock.
- Quando queremos indicar que se trata de horas antes ou depois do meio-dia, usamos as expressões ante meridiem (antes do meio-dia) e post meridiem (depois do meio-dia) que são abreviadas a.m. e p.m. Observe:

It’s seven a.m. (São sete da manhã)It’s five p.m. (São cinco da tarde).
- Existem dois modos o Americano e o Britânico para se dizer as horas:
