Short description of the client's issue:
The calendar portlet does not properly display the pop-up calendar correctly (used when creating or editing events) when the browser window is viewed at a zoom level. Changing the zoom levels will inaccurately show the calendar in that zoom level.

Steps to reproduce / testing done:
1. Go to the calendar portlet. Zoom out to 75%.
2. Create or edit an event.
3. Click on the calendar icon under Start Date (for create and event) or Repeat (for editing an event).

Results of steps / testing:
The popup calendar does not show correctly. The are only six number dates per week (not seven) even though there are seven days shown.

Errors/logs:
Please see attached screenshots for behavior in 6.1.20 and 6.1.X where the issue is exhibiting, and Trunk, where the issue has been resolved.

Testing in 6.1.X
Issue is replicated
