This library makes it possible to convert Oxford dates to real dates and vice versa. It creates a new OxfordDate object to represent Oxford dates, and adds a .toOxfordDate() method to new Date objects.

OxfordDate objects have the following properties and methods:

• Term: Term object reprsenting the term
• Week: Week in the term
• Day: Day of the week (0=Sunday, 6=Saturday)
• toRealDate(): Return the real date represented by the object

function Term(realDate)

This is the constructor for the Term object. The Term object has the following properties:

• term.StartDate (Date object)
• term.TermName (string)

Example:

term=new Term(new Date());
alert(term.TermName+" term "+term.StartDate.getYear()+" starts on "+term.StartDate.toString());

function CreateTerm(year, termNumber)

termNumber:

• 0=Hilary
• 1=Trinity
• 2=Long Vacation
• 3=Michaelmas

This function returns a Term object for the term and year specified.

Example:

term=CreateTerm(2006, 3);
alert("Michaelmas 2006 starts on "+term.StartDate.toString());

function OxfordDate(term, week, day)

Create a new OxfordDate object. The term argument must be created using the CreateTerm function, or by passing in an existing OxfordDate's Term property.

Examples:

oxDate=new OxfordDate(CreateTerm(2006, 0), 1, 0);// Sunday 1st week, Hilary 2006
today=(new Date()).toOxfordDate(); // Get today as an OxfordDate
oxDate2=new OxfordDate(today.Term, 5, 6);// Saturday 5th week of this current term
