How It Works

Meaning

Prepositions of time are used to indicate when an event occurs. They help specify time frames, dates, and durations. Common prepositions of time include at, on, and in. Mastery of these prepositions is important at the B2 level to enhance clarity in both written and spoken communication.

Use it when

  • Describing specific times or moments (e.g., at 5 p.m.)
  • Referring to days and dates (e.g., on Monday)
  • Indicating months, years, or longer periods (e.g., in 2020)
  • Talking about the duration of an event (e.g., for two hours)
  • Specifying time limits or deadlines (e.g., by next week)
