Telling the Time in English: From Shift Start to Last Call

CEFR A2  ·  5 min

From my experience:

At Merivale in Sydney — the group that runs The Ivy, Uccello, and Establishment — a shift started at 5:30 PM and ended at 2 AM. Time was everything. A five-minute delay could mean a cold plate arriving at the wrong table. Knowing how to say and read time in English was not optional.

Today's focus: Telling the time: o’clock, half past, quarter to/past, 24-hour

British-style (most common in formal contexts):

  • 6:00 = six o’clock
  • 6:15 = quarter past six
  • 6:30 = half past six
  • 6:45 = quarter to seven

American/informal style:

  • 6:30 = six thirty  |  6:45 = six forty-five

24-hour (schedules, professional): 18:30 = eighteen thirty. Never say ‘eighteen thirty o’clock.’

Examples in context

Service starts at half past five. (5:30 PM — British style)
Last call is at one forty-five in the morning. (1:45 AM — American/informal)
The reservation is at 19:30. Please arrive by 19:15. (24-hour — hospitality standard)

▶ How do you say 7:45 in British style?
✓ Answer: Quarter to eight
7:45 is 15 minutes BEFORE 8:00, so it’s ‘quarter TO eight’ — not quarter past seven.
▶ Is ‘fourteen thirty o’clock’ correct?
✓ Answer: No. In 24-hour time, just say ‘fourteen thirty.’ Never add ‘o’clock’ to 24-hour times.
14:30 = fourteen thirty. ‘O’clock’ is only for 12-hour times on the exact hour: six o’clock.
▶ A guest says ‘Let’s meet at half seven.’ What time is this?
✓ Answer: 7:30 — ‘Half seven’ is a very common British informal expression for 7:30.
In German, ‘halb sieben’ means 6:30 (half TO seven). In English, ‘half seven’ means half PAST seven = 7:30. Important difference!
⚡ 5-second rule:

Learn both styles: half past / quarter to (British formal) and six thirty / six forty-five (American/informal). Both are correct — context decides which to use.
