In this guide, I’ll shed light on these tricky terms, focusing specifically on how they’re used to indicate time and place. With a bit of practice, you’ll find that grasping these prepositions is easier than it initially seems.

So let’s dive right into the world of ‘in’, ‘at’, and ‘on’. By the end of this article, you’ll not only understand when and where to use them but also why we use them in those specific instances. Buckle up because it’s going to be an enlightening ride!

Understanding ‘In, At, On’: An Overview

Diving straight into the subject of prepositions of time and place, let’s tackle three common ones: ‘in’, ‘at’, and ‘on’. It’s essential to note that these words play a crucial role in English grammar. They help us understand when or where something happens, adding context and clarity to our sentences.

Starting with ‘in’, we use this preposition for unspecific times during a day, month, season, year. We also use it when referring to a larger area where something takes place. For example:

  • I usually wake up early in the morning.

  • They went on vacation in July.

  • The flowers bloom in spring.

  • He was born in 1980.

  • She lives in New York City.

Looking at ‘at’ next, we use this preposition for specific times and places. Like so:

  • The meeting is scheduled at 3 PM.

  • You’ll find him waiting at the bus stop.

Finally comes ‘on’, used for days and dates as well as surfaces:

  • Let’s meet on Wednesday.

  • His birthday falls on April 20th.

  • The cat slept soundly on the mat.

To provide you with a quick reference guide here are some examples together in one place:




In July; In the morning; In 1992

In New York City


At 3 PM; At midnight

At the bus stop


On Wednesday; On April 20th

On the mat

We’ve just scratched the surface of how these prepositions work! There’s more to learn about their usage in different contexts but this should give you an understanding of their basic functions within English grammar.

Practical Examples: Using ‘In, At, On’ in Daily Conversation

Let’s dive straight into it. The prepositions ‘in’, ‘at’, and ‘on’ may seem trivial but they can dramatically alter the meaning of a sentence. It’s paramount to understand their correct usage in daily conversation.

Firstly, consider the preposition ‘in’ which is often used with months, years, seasons, and parts of the day. For instance:

  • I was born in December.

  • He graduated in 2010.

  • We enjoy hiking in the fall.

  • I prefer jogging in the morning.

Next up is ‘at’, usually applied to specific times on a clock or specific locations. Here are some examples:

  • Let’s meet at 5pm.

  • She’s waiting for you at the entrance.

Lastly, we have ‘on’, commonly used with days of the week or dates. See these sentences:

  • My appointment is on Tuesday.

  • Their wedding will be held on August 15th.

To provide an even clearer understanding, here’s how these prepositions work within a single context:




We’re going on vacation in July


Meet me at our usual spot


Don’t forget our meeting on Friday

Remember that while there are rules governing their use, exceptions exist too. Like most aspects of language learning, practice makes perfect! So don’t be afraid to experiment with these prepositions in your everyday conversations until you feel comfortable using them correctly.

Finally (and this is important), don’t let small errors discourage you! Even if you stumble at first while using these words – keep trying! After all, every mistake is a step closer to mastering English grammar.
