The DOB on my passport data page is 14th Dec instead of 13th Dec and?
Dont wait too long. The longer you wait to correct it the more difficult it will be to fix the issue. When you go in the State Department website you can type in a new application. I think you will also have to do a DS5504z it depends on how long you waited. However you cannot do it now as the State Department is more or less closed right now.
