Add to Cal

Add any project time frame to your preferred calendar application with a single click.

What does this plugin do?

This add-on allows you to add any project time frame to your preferred calendar application with a single click. Once activated, a button will appear next to any project that has a due date specified.

There is also a setting to show the Add to Cal button on all projects, regardless of if they have a due date specified or not.

When the Add to Call button clicked, the project title, URL, start and end dates (if the project has any) and description (if it has one) will be added to your preferred calendar application.

How do I activate the plugin?

Activate the add-on like you would any other WordPress plugin. Go to Plugins -> Installed Plugins -> Add to Cal and hit the Activate link.

Once the add-on has been activated, you will see a new tab in Task Rocket settings call Add to Cal where you can change settings.

What options can be set with this add-on?

  • Google calendar (web)
  • Yahoo calendar (web)
  • Microsoft calendar (web)
  • iCal compatible desktop calendars (Outlook, Apple & others)

The iCal compatible desktop calendars option will show all choices on the front-end.

The condition to show the button: The option Show on all projects will show the Add to Cal button on all projects, regardless of if they have a due date specified or not.

Why can't I see the Add-to-cal icon on a project?

In order for the Add-to-cal icon to show in a project, the project needs to have at least a due date.

The only time is this is not case is when you’ve enabled the ‘Show on all projects’ option, in which case the Add-to-cal icon will show on all projects regardless of if they have a due date or not.


If for some reason you are experiencing issues with the open graph meta tag values not being populated, you can try using the troubleshooting options.

The will attempt to change the priority of the open graphite functions so that they are not interfered with by other plugins or themes.

Only use these options if you are the experiencing issues mentioned above.
