So you want to keep your Google calendar import in sync with JEvents - How do you do this?

  1. Create a 'From URL' calendar in JEvents
  2. Use the URL for the ICS export from Google in the URL field
  3. Save (this does the initial import).
  4. In the list of calendars click the icon in the "Anon Refresh" column
  5. Copy the link from the URL that then appears beneath this icon
  6. Use this URL in a cronjob that fetches this URL as frequently as you want.

You could use an online service like Setcronjob to do this for you.

If you want to run this using a cronjob on your unix based server then this is the entry in the cron file that I use:

1,31 * * * * /usr/bin/curl -s http://www.mydomain.com/index.php?option=com_jevents&icsid=6&task=icals.reload > /dev/null 2>&1

of you could try

1,31 * * * * /usr/bin/wget -O /dev/null "http://www.mydomain.com/index.php?option=com_jevents&icsid=13&task=icals.reload" > /dev/null 2>&1
