date validation during input

PCRE (PHP <7.3)
this regex is able to validate a date (format dd.mm.yyyy) in every state of user typing. i use it to ensure that the user isn't able to type in an invalid date at all (except from a leap year check which is done afterwards) The regex also makes assumptions of 'missed' separators so 1234 is captured...
