Does the expression "within the same day" make sense? I want to say something like "if I go today, I can't come back within the same day," or "I if I get banned from a forum, I can't log in within the same day." Or, like, "I can't post the same thing twice within the day."

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. If this question can be reworded to fit the rules in the help center, please edit the question.
While it's not technically wrong, it's confusing because "within the same day" can mean within the same calendar day or within the same 24 hours. It's typically better to say "If I've been banned from the forum, I can't post anything for 24 hours."
It might be written in the sense of “within the given time”. But it is technically improper using “within the same day”. For example:
I can complete the work within 4 hours.
But this sounds improper:
I can complete this work within the same day.
