Prepositions of time are used to indicate when something happens. The most common prepositions of time are "at," "on," and "in." Here’s a detailed overview of each, along with examples:
1. At
Specific times: We use "at" for specific times on the clock and specific points in time.
Examples:
At 5:00 PM: "The meeting starts at 5:00 PM."
At noon: "Let's have lunch at noon."
At midnight: "She always goes to bed at midnight."
Specific holiday periods: We use "at" for holiday periods and certain expressions.
Examples:
At Christmas: "I love being with my family at Christmas."
At Easter: "We often go on vacation at Easter."
At the weekend (British English) / On the weekend (American English): "What are you doing at the weekend?"
2. On
Days and dates: We use "on" for days of the week and specific dates.
Examples:
On Monday: "She has a meeting on Monday."
On July 4th: "We celebrate Independence Day on July 4th."
On Christmas Day: "They visit their grandparents on Christmas Day."
Specific day parts: We use "on" for specific parts of a day when referring to a particular day.
Examples:
On Monday morning: "I have a doctor's appointment on Monday morning."
On Saturday night: "We are going to a concert on Saturday night."
3. In
Longer periods: We use "in" for longer periods of time such as months, years, centuries, and long periods.

In April: "The flowers bloom in April."
In 2024: "They plan to graduate in 2024."
In the 21st century: "Many technological advancements occurred in the 21st century."
Parts of the day: We use "in" for parts of the day, except when referring to a specific day (then "on" is used).
