Prepositions in, on, and at
When to use which?
In a nutshell
In
1. Using "In"
"In" generally refers to something enclosed or within the boundaries of a space or time frame. It suggests a position inside a larger area or period. It's used for more general contexts.

The conference will be held in New York City.
Enclosed or defined spaces:
The keys are in the drawer.
The book is in the box.
Bodies of water:
There are fish in the lake.
The ship is in the Pacific Ocean.
B. Time (Periods and Lengths)
Months, years, centuries, and long time periods:

This tradition started in the 18th century.
Seasons:
We go hiking in the summer.
Periods within the day:
He will come in the morning/afternoon/evening.
Duration (how long something takes):
She will finish the project in two days. (i.e., within two days)
C. Other uses:
Transport (when referring to cars or smaller vehicles):
She is waiting in the car.
Written or printed material:
I read it in the newspaper.
On
2. Using "On"
"On" refers to something attached to or touching a surface. It often indicates position atop a flat surface or the idea of being in contact with something.
A. Location (Surface or Position)
Surfaces:

There’s a stain on the floor.
Public transport (planes, trains, buses):
He is on the bus.
I’ll meet you on the train.
Technology (when referring to devices or the internet):

Roads and streets:

B. Time (Specific Days or Dates)
Days of the week and dates:

The event is on July 4th.
Special days or occasions:
They got married on Christmas Day.
C. Other uses:
Referring to being involved in activities or projects:
I’m working on a new project.
Parts of the body (when something is physically on you):
She has a ring on her finger.
At
3. Using "At"
"At" is used for specific points or precise locations in both time and space. It focuses on exactness rather than something enclosed or on a surface.
A. Location (Precise Points)
Specific addresses or locations:
He lives at 123 Main Street.
I’ll meet you at the entrance.
Points of reference:
They are waiting at the bus stop.
Let’s meet at the corner.
Locations with activities (e.g., events or places with particular purposes):
We had lunch at a restaurant.
She’s studying at the library.
B. Time (Specific Times)
Exact times:
The meeting starts at 9 AM.
Let’s meet at noon.
Holidays without "day" in the name:
They always travel at Christmas.
We’ll see you at Easter.
C. Other uses:
Speed, temperature, and rates:
The car was traveling at 60 mph.
Water boils at 100°C.
Exceptions
Special Cases and Idiomatic Expressions
Some uses of in, on, and at don't follow the typical rules:
In the morning, in the afternoon, in the evening (but at night).
On time (punctual), but in time (before a deadline).
At work, at school, but in class or in school.
On foot (walking), but in a car (inside a vehicle).
Key take away
Choosing between in, on, and at depends on the context, particularly whether you're referring to a general location/time (use "in"), a surface or specific day (use "on"), or a precise point (use "at"). With consistent practice, the usage of these prepositions becomes more intuitive.
