Expert writing Tips

Best practice

When asking about a specific day, use the preposition "on" instead of "at". For example, use "on what day" is the meeting scheduled?

Common error

Avoid using "at" when referring to specific days; "at" is generally used for times (e.g., "at 3 PM") or locations. Always use "on" when specifying a day of the week or date.
