The joys of ISOdates

By

It took me a fair while to get comfortable with the ISO 8601 date format. After so many years of using DD MMM YYYY, my old eyes and brain had some trouble understanding YYYY-MM-DD. Finally something clicked, and I now read 'ISOdates' easily and I really appreciate their advantages. The biggest…
