Understanding Time Expressions

Specific time expressions are crucial in communicating effectively. The distinction between using 'at', 'on', and 'in' is highlighted, where 'at' is used for precise times, like 'at 2:30' or during specific meal times, such as 'at lunch'. In contrast, 'on' is applied to days of the week and specific dates, like 'on Monday' or 'on Christmas Day', showing a clear connection to particular days. Lastly, 'in' is utilized for broader time frames, such as seasons and months, reinforcing the need to grasp the appropriate contexts for each expression.
