Subscribe to a calendar

Subscribing to a calendar means establishing a connection with the calendar so that you automatically receive calendar updates. You can set up that connection in several different ways.

I already subscribed to a calendar. I want to unsubscribe. How do I do that?

This topic describes all of the available subscription options. Some options depend upon settings the calendar publisher enables or the calendar program and operating system you're using. That means your list of options may not look exactly like this one.

Why does my subscription include events I didn't see in the calendar?

You were probably looking at a filtered calendar view at the time you subscribed. When you set up an email subscription using the Subscribe link, you see all of the events in the email you receive, not just events in the filtered view. If, at the top right corner of a calendar, you see an RSS button similar to the one outlined in red below, click that button to set up a feed subscription to the filtered view.

RSS feed button

Daily (or Weekly, Monthly, etc.) email

This option is available if the calendar publisher turned on email subscriptions. Subscribing to an email means that, if you provide a valid email address, you'll receive regular upcoming-event email messages from the calendar. You can stop receiving the messages at any time by clicking an unsubscribe link in the email footer.

Note When you subscribe to a calendar email, you make your email address available to the calendar publisher.

More about calendar email

Calendar email is scheduled email sent from a calendar to people on a distribution list. Calendar email messages contain lists of new, updated, and upcoming events. If events included in the message interest you, you can add them directly to your personal calendar, set up reminders, forward event information to friends, and take other actions.

Example calendar email

The calendar email message you receive will look something like this. To add an event to your personal calendar or take other actions, click the icon Event actions icon.

RSS Feed or Atom Feed

RSS and Atom feeds are types of XML code used to feed ever-changing news, events, or other data to you. Setting up a feed allows you to stay up to date without having to constantly revisit websites.

By subscribing to a calendar's feed, you'll receive feed updates every time new events are added.

Note The feeds include a maximum of 1000 events or fewer, as set by the publisher.

    • If your browser displays feeds or supports feed reader extensions, a browser window opens and you have the option to subscribe.

More about RSS and Atom feeds

Recent versions of common web browsers display feeds right in the browser. After the feed displays, you can decide whether or not to subscribe.

If your web browser doesn't display feeds, you can view and subscribe to feeds from a program called an RSS or news reader or aggregrator. Many feed readers are available free on the web. To find out about a few of them, you might start by searching the Web for "rss reader."

Most news readers and browsers treat RSS and Atom feeds the same way. The XML code for the two feed types does differ, however. For a brief overview of the differences, try the Atom Compared to RSS 2.0 section of the Atom page in the Wikipedia.

Tip If you use an Atom news reader and your browser can't display Atom feeds, subscribe to an RSS feed to display the feed URL. Copy the URL and paste it into your feed reader, then replace .rss in the URL with .xml.

  • Apple® Calendar (or another program that supports iCalendar) with Mac OS® X or later.
  • Windows Calendar, Microsoft® Office Outlook® 2007 or later, or another calendar program that supports iCalendar with the Windows Vista™ (or later) operating system.

More about iCalendar feeds

iCalendar is a standard format for calendar data. When programs support iCalendar, event information can be easily exchanged between them. However, you still need some way to move the calendar information from the one place to another. That's where webcal comes in. Webcal is a protocol for delivering iCalendar-formatted information over the internet.

When you subscribe to an iCalendar feed, your browser encounters a webcal URL. Most current browsers automatically hand this URL over to your calendar program. If your calendar program supports the iCalendar format, it downloads the event information and establishes a connection with the online calendar so new events will automatically be passed on.

If you use more than one calendar program (for example, Google Calendar and Outlook), you can control which program a browser opens when you subscribe via an iCalendar URL.

  1. In your browser, follow instructions for how to set which programs handle specific file types and protocols.
  2. For the .ics file and/or webcal protocol handler, set the calendar program you prefer.

Tip You can set different .ics and webcal handlers in each browser you use.

Download iCalendar File

Downloading an iCalendar file downloads a current snapshot of events starting from the current day.

The iCalendar file will have an .ics extension (for example, downloadedcalendar.ics). Depending upon which calendar program and web browser you use and what your browser security settings are, your calendar program may automatically open the .ics file. Otherwise, you can save the file to your computer and import it into your calendar program.

Note Downloading an .ics file does not establish a connection with the online calendar. Events added to the online calendar after you download and open or import the .ics file will not be added to your personal calendar.

To download an iCalendar file

  1. Select Download iCalendar File, and then click Download iCalendar File.

    Download iCalendar File option and button

  2. What happens next depends upon what calendar program and browser you use and your browser's security settings.
    • Your calendar program may open and display the downloaded file as a new calendar.
    • Your calendar program may open and prompt you to choose the calendar to which you want to add the downloaded events.
    • Your browser may give you the choice of identifying the program in which you want to open the downloaded file.
    • Your browser may give you the choice of saving the file to your computer.
    • If your browser security settings don't allow files you downloaded to open automatically, save the file to your computer.
    • If your browser security settings don't allow you to download files, you may want to change the settings under Preferences or Options.
  3. If you save the file to your computer, open your calendar program, and import the file you saved.
