FAQ

Different calendar systems have different ways to obtain the feed URL. You may need to consult your calendar software’s documentation for assistance. Find instructions for commonly used calendars below.

You will also need to make sure that your calendar is public. Private calendars cannot be accessed by this plugin.

Documentation quick links:

Use this shortcode, inserting your ICS feed URL between the quotation marks:

[ics_calendar url=""]

Be sure you are using the iCalendar subscription (ICS) URL (i.e. for importing into a calendar program), not the URL for viewing a calendar in a web browser. To test if you have the correct URL, paste it directly into your browser address bar. It should download an .ics file, not display the calendar in the browser.
