Read a simple schedule and ask when a place opens or a service leaves.

The idea

Use on with a day: on Monday. Use at with a clock time: at nine. Ask What time does the shop open? to find the opening time. Timetables can use the present simple for scheduled events: The next train leaves at ten thirty. Repeat the day and time to confirm.

Examples

  • The class starts at nine.
  • The library opens on Monday.
  • The next train leaves at ten thirty.
  • The museum is closed on Sundays.
  • What time does the shop open?
  • Is the office open on Friday?

Watch out

A day and a clock time take different prepositions in these examples: on Monday but at nine. Opening days do not automatically tell you the closing time.
