Expert writing Tips
Best practice
When using "in the PM", ensure clarity by specifying the exact time (e.g., 3 PM) to avoid ambiguity, especially in formal settings. If the context already makes it clear that you are referring to the afternoon or evening, consider simply using "in the afternoon" or "in the evening".
Common error
Avoid omitting the "AM/PM" designator when the context does not clearly indicate whether you are referring to a time in the morning or the afternoon/evening. This is particularly important in scheduling or time-sensitive communication.
