Typing into a field which does not accrue characters in the usual manner
seems likely to lead to confusion.  You probably need to prevent, or
consider, mouse actions in the field.

Instead, why not type into an initially empty field, which accepts what
is typed in the usual fashion, and have above it a readonly field which
displays the date currently indicated.  At each keystroke, and perhaps
at each mouse action - or alternatively every 25 milliseconds - read the
input string, apply it by your algorithm to the default date, and show
that in the readonly field, which is what will be used when submitted.

It would be possible, and might be useful, to change the colour of the
readonly field when, as is, it represents an invalid date - either
because it is non-Gregorian or because it is outside the range that the
application should accept.
