How do I merge external calendars?
The Merge External Calendar option allows you to subscribe to external calendars such as an institutional calendar, or a web calendar (Google Calendar, Outlook, etc.) in iCalendar format.
Note: This feature has some limitations:
-
It does not support all-day events.
-
It only supports events defined with VEVENT from the iCalendar specification.
-
It does not support events without an end time.
Also note that new or revised events in external, subscribed calendars may not appear instantly in Sakai. Synchronization with subscribed calendars occurs approximately every 30 minutes.
Go to Calendar.

Select the Calendar tool from the Tool Menu in your site.
Click Merge External Calendars.

Enter iCalendar subscription information.
In the bottom section of the page, enter a Calendar Name and URL for the calendar to which you would like to subscribe. Typically the URL you enter should have a suffix of ".ics". Then click the Subscribe button.
When subscribing to a new external calendar, clicking Subscribe will suffice for saving the subscription; you do not need to also click the Update Subscriptions button as described below, assuming your only intent is to subscribe to this new calendar you have entered.
Select institutional calendars.
If there are any institutional calendars available within the system, you may subscribe to them by selecting the check box in the Subscribed? column. Note that to save your subscription, you must also click the Update Subscriptions button as described below.
View subscribed calendars.
Any currently subscribed calendars will appear listed at the bottom of the page under the heading Other External Calendars.
Click Update Subscriptions.
You can unsubscribing to a calendar listed under Other External Calendars by unchecking Subscribed?
Once you have made all of the desired edits to the checkboxes for calendar subscriptions, click Update Subscriptions.
Clicking Update Subscriptions will remove unsubscribed calendars from the listing under Other External Calendars. A warning regarding this will display in a popup window allowing you to confirm or cancel the action.
