Best practice
When using "on a different day", ensure the context clearly specifies or implies the original day being referenced to avoid ambiguity. For instance, "The meeting was scheduled for Monday, but we moved it to on a different day."
Common error
Avoid using "on a different day" without providing context or reference to the initial day. This can confuse the reader or listener. Instead of saying, "I'll do it on a different day", specify, "I'll do it on Tuesday instead of Monday."
