Where is Date Syntax Used?

⚫ Applications that incorporate a date (birth date,

anniversary, due date, appointment date, deadline, calendar event, etc.)

⚫ Programs that analyze textual input and find all dates ⚫ Program that perform computation with dates: days

between, day of the week, date of special days, how many days you've been alive, etc.

Finding Date Syntax Samples

Gather as many examples of date syntax as you can

⚫ Search your computer and external systems for various

representations of a date and develop a description of each representation in BNF or EBNF.

⚫ Note: there are at least 12 commonly used

representations, and perhaps more.
