Is your requirement to check that the string represents an actual date? Or will you accept "31/02/2011" as valid?

Not the current date, just a date in that format

Checking if a String represents a valid usually means parsing that String into a Date. There are several threads about that; I've posted in quite a few of these already.
And what Paul meant is disallowing invalid dates like February 31st. You can make the date format non-lenient to disallow this.
