Week Numbers is a small utility with the only purpose, to add week numbers to iCal calendars as all-day events. The numbering can be added (and removed again) from any of your calendars. Depending on the iCal settings, ISO 8601 or US week numbering scheme is applied.
v1.2 [Aug 22, 2012]
Bugfix:
Checks now for a missing "first day of week" entry in the iCal .plist file and alerts the user to force this setting from the iCal preferences panel.
