Urgent: To get data from Time hierarchy

Hi,

We have a Time Dimension as below :
[Time].[Time calendar date]
[Time].[Time calendar week hierarchy].[Time calendar week]

Presently we are displaying stocks till a week , but now requirment is
to display stocks till a week + 1 day (where week starts on monday).
How can i take/relate the data of next day of week that is Monday.

Please treat this as an very URGENT requirment.

Thanx in advance.
