To give you a short and convenient reference, the preceding code contains several commonly used date formats. Depending on where you are, the order in which day, month, and year are used might vary:
In the United States, it's (mostly) month, day, and year
In the United Kingdom and the rest of Europe, it's (mostly) day, month, and year
The international standard date notation starts with the year and continues with month and day
NOTE
The preceding code used a four-digit representation of the year because this is nonambiguous. In practice, however, two-digit years are also commonly used.
