For the average user, there is no big difference between the various date formats one typically runs across. When you take a close look at computer programs, however, you will find that in some cases the order is day / month / year (DDMMYY), while in others it is year / month / day (YYMMDD), and there are many other combinations of these three elements.
事實上，儘管在使用者看來，電腦的日期顯示方式似乎大同小異，然而深入程式中會發現，有些日期的順序是日月年（DDMMYY），有些是年月日（YYMMDD），以及各式各樣的三者組合。
