The default range of Year (Two Digits) section under Tools -> Options -> LibreOffice -> General is 1930 (to 2029). It has been so ever since the first LO release 15 years ago, probably even longer back in OO days. Since we're getting very close to the end of the range, I would suggest bumping it by 20-30 years. How does 1960 sound? The default is here: https://opengrok.libreoffice.org/xref/core/officecfg/registry/schema/org/openoffice/Office/Common.xcs?r=3c12bd0f084e74fe4ca98db50b454af5ef2b96d9#3614 Config: TwoDigitYear
Just checked a Windows 11 (25H2 26200.7462) install, and MS has already moved the os handling of two-digit year entry to the 1950 - 2049 pivot, from 1930 - 2029 implemented at Y2K. Internally ODF requires ISO 8601 date handling, so the two-digit year interpretation is *just* a filtering action left up to the application. Agree it is not too soon to adjust, but I'd suggest moving the 'TwoDigitYear' value to '1950' with the 1950 - 2049 range to track with MS, rather than more aggressive 1960 - 2059.
Created attachment 205035 [details] 2digit-year handling at Win11 25H2 Internally LibreOffice keeps dates as ISO 8601, so the 2-digit year "interpretation" is just a UI function and may or may not need to take input from os/DE. I don't think LO does, and the 'TwoDigitYear' value in Common.xcs just sets the cross over.
