DataGridView: Time sheet similar to Outlook Calendar

I need to create a time sheet for employee in datagrid view, where employee can select working hours of each day. I want to display DataGrid in such a way that hours of day appear as columns (24 columns) and rows appear as days (30-31 depending upon month), similar to Outlook Calendar thing where we select number of hours for some event on a particular day. So that when employee selects cells I can get work time from corresponding selected columns. Can some one point me to direction how I can label my rows and columns with dates and time.
