See the example of use of the DateTimeFor here: BinariesWithSimpleExamples 

Basically:

@{var DT = DateTimeFor(m => m.ExpiryDate, dateInCalendar : true)}

@DT.DateCalendar(
                    inLine: false,
                    calendarOptions: new CalendarOptions
                    {
                         ChangeYear=true,
                         ChangeMonth=true,
                          
                    },

containerHtmlAttributes: new Dictionary<string, object> {{"class", "expirydate"}})

There are various calendar option you can choose....I put the ones I like more

I have chosen to use the jQuery picker, so you have to include the relateive js files, and css
