Being and older developer, I remember all the fuss about the Y2K bug. For the younger readers, shortly before the millennium, there was huge panic that mankind would suffer enormous catastrophe as we moved from the year 1999 to 2000. The cause of this concern was the short-sighted way some computer programs had been storing dates. We had been using a couple of numbers to store the year - like 77 for 1977 and 85 for 1985. Developers of that early software had made the assumption that their programs would not be running by 1999 and therefore thinking about numbers greater than 99 (1999) was not required.
