Created attachment 206316 [details] Screenshot in Word This is after the fixes of bug 164694, and bug 169101 in 26.8, but it was never OK as far as I know. Open the simplified reproducer from bug 153097, attachment 184770 [details], change the date in the header to a different year, eg. 2012, and save it back to DOCX. Open result in Writer or Word. => Date picker shows the old date, in Word it even looks smaller than before (size is okay if file is roundtripped without a change).
