      This smacks of a Julian/Gregorian date algorithmic scheme to extend the legit dates that can be managed in 2 bytes. . . . Last Old Dog

        That's only 27 years. My Land Rover is 47. I guess it says something about how long they expect their product to last. Or maybe how long they expect to stay in business?

          It must be moot since the calendar we currently go by only lasts 13 years (IIRC) before it repeats itself.

              There is more to it. For years (yea, a bunch) we have been assigning a sequential number to each day. So as time goes on, this number (we called it the Julian Number) would increment by one each day, year after year.

              This number was then used to calculate days between dates as used for aging in accounting, banking, and many other fields. Simply subtract one from the other. In all the computer software we wrote, the actual Gregorian date (the calanddr on the wall) was converted into this sequential number and stored in that very compact space saving way. When a date was requested from a file, the computer employing a quick algorithm would convert it to MMDDYY, DDMMYY, MMDDYYYY, or what ever format you wanted. And it made adjustments for leap year too. Invaluable for calculating days between dates.

              Can you imaging trying to calculate with any accuracy the number of days by hand? There are not exactly 4 weeks in a month nor 52 weeks in a year. . . . .Last Old Dog
