Ok, assuming that the due date for this particular paper is on the 20th of March.
Would it be reasonable for me to assume that I can still submit the paper at 11:59PM on the 20th of March?
I recently submitted a paper where the due date (say it's) on the 20th of March. But around 10am on the 20th, the system didn't accept any more papers and the submission has been closed : /
Or does it play no part?
