On dates and stuffed non-dates

By

Nothing gives my wife the Screaming Meemies like dates in spreadsheets. Unless she formats the target cell in advance as text, the spreadsheet will turn a perfectly innocent, non-date string like 23/2/6 into '23-Feb-2006'. When she types 6420-11-3, according to both LibreOffice Calc and Gnumeric,…
