Your deadlines don't apply to Apple. When you resubmit, you go back to the end of the queue.
Apple says most submissions are reviewed within 48 hours. Many people on this forum complain about delays lasting weeks. So obviously, the many people who are getting their apps reviewed in a few hours aren't complaining.
Generally speaking, deadlines aren't compatible with the App Store. There is an option to manually release your app on your own schedule after it's approved. But you'll need to submit your app well in advance of that deadline.
