At, On or In? Prepositions of Time Made Easy

Prepositions of time are one of the most common challenges for English learners. Should you say 'at Monday', 'on Monday' or 'in Monday'? In this video, you will learn a simple trick to get it right every time. Start with the quiz: 'The meeting starts ___ 3 PM.' The correct answer is 'at'. Here is the rule. Use 'at' for exact times, like at 3 PM, at noon or at midnight. Use 'on' for days and dates, like on Monday, on July 4th or on my birthday. Use 'in' for longer periods, like months, years, seasons and parts of the day, such as in October, in 2026, in summer or in the morning. A helpful way to remember it is to think of a pyramid: 'in' is the biggest period, 'on' is medium, and 'at' is the most specific. There are a few exceptions, like 'at night' and 'at the weekend' in British English, so learn them as fixed expressions. Now it is your turn. Complete the sentence: 'The meeting is scheduled ___ Monday.' Watch the video, check your answer, and write it in the comments to practice.
