Help wanted.
Consider a table having these values.

01.07.2010 9hrs
02.07.2010 9hrs
04.07.2010 9hrs

Now i need the dates that do not have hours. i.e on 03.07.2010 there are no hours in this table.But I need that date value. Basically i need to know which all dates do not have hours from this table. I need to know the dates that are not present in this table and the date can from 01.02.2010 and 30.02.2010. Can anyone please help me on this logic. I am not able to get a javascript logic to get the dates that do not have an entry in this table.
