Can I subscribe to the home page calendar?

The iCalendar subscriptions from the home page calendar allows you to add your milestones, tasks, and notes to your favorite desktop or web-based calendar software. These instructions detail how to obtain the URL for your iCalendar subscription and add it to Google CalendarApple iCal, or Microsoft Outlook (2007 or later) or to download an iCal file.

A note about authentication

The iCalendar URL does not require any authentication when you subscribe to it with your calendar software. Do not share your iCalendar URL with anyone — your iCalendar URL is unique to your Intervals account and includes your milestones, your tasks, and your notes.

How often will my calendar update?

The rate at which your calendar refreshes itself depends on the iCalendar software and its settings.  The software might refresh the iCalendar subscription every 30 minutes, or only once a day. If you don’t see your calendar changes showing up as soon as you would like, look at the settings or follow up with the software vendor.

Where to Find the URL for Your iCalendar Subscription

The first step in setting up your iCal subscription URL is to decide what should be included in it. To do this, use the filter options in the right column of the home calendar. For example, you might want to filter the calendar milestones and tasks by a certain client. Once the filter options have been selected, click the “Filter” button to redraw the calendar. If you prefer to download an iCal file instead of a subscription please click on the “Download” option.

Subscribe to calendar

Next, hover your mouse over the iCalendar icon (pictured above) and select “Subscribe” from the drop down menu. This will bring up a lightbox window (pictured below), with the URL for your iCal subscription. Click on the “copy” icon to save the URL to your clipboard. You are now ready to set up your Intervals calendar subscription using your preferred desktop or web-based software.
