phpCollab contains a calendaring component, which is integrated with project tasks and allows the user to manually add items only to the calendar. The calendar is optimal for meetings, milestones/deliverables, and other events.

To add an event to the calendar, click on "Calendar" in the main navigation, located at the top of every page. The current month page will load - to add an event to a different month, click on the "Previous" or "Next" link at the bottom left of the page. Click on the day link located in the top right hand corner of every day on the calendar page. The main page for that day will appear - click the Add button.

The "Add Event" Page will appear with the following fields:
Subject (the long name of the event)
Description
Short Name (required - will appear in the day)
Start date (defaults to day you selected) - change manually or using calendar button
End date(defaults to day you selected) - change manually or using calendar button
Start Time
End Time
Reminder (Yes or No)
Event recurs... (Checkbox) - Note: there is no ability to change the end date or type for recurrence
Click the "Save" button to add the event. To edit the event, navigate back to the calendar day page, click the box next to the event and click the Edit button. To delete the event, click the Remove button in the same manner. You can also export the event as an iCalendar file using the Export button. Note: there is no ability currently to publish to or view the calendar on the Project Site.
