Edit Date on Screenshot

I have a single screenshot that shows a date in the upper-most section of the image, and I need that date updated to a new one while keeping everything else untouched. The change has to look completely natural—matching font, size, colour, and any surrounding shadows or anti-aliasing—so no one can tell it was modified. Please work on a copy so the final file is delivered back to me in the same resolution and format as the original, with no compression artefacts. A quick turnaround would be appreciated; it’s only one date, so I expect this to be a straightforward retouch for anyone comfortable with Photoshop (or an equivalent editor). Once I confirm the new date looks seamless, we’re done.
