You might want to have instant visibility to a co-worker schedule. In this case, you can subscribe to their calendar. To add a co-worker's calendar, select, "Add other calendars," at the top of the other calendars list. Select, "Subscribed calendar," and type the person's name in the add Calendar box. Google Calendar will suggest people as you type. If you have permission to view the calendar, it will be added to your other calendars list. After the calendar is added, you can also set event notifications and other notifications settings for that calendar. In addition to co-worker's calendars, you can also browse resources and calendars of interest, add a public calendar via URL, or import a calendar from a file in iCal or Outlook CSV formats. As discussed previously, resources are centrally managed calendars, that represent a shared location or thing. Calendars of interest include religious and regional holidays, major sports team schedules, and phases of the Moon. If you have multiple calendars, you can show and hide the events on each calendar using the check box to the left of the calendar name in your list. If you haven't already added a colleague's calendar, do so now. Then "Check" and "Uncheck" the box to the left of your colleague's name to view this behavior. You can also choose a color for each calendar to make it easy to determine which events belong to each calendar. Google Calendar allows you to create additional calendars to schedule for a project, an event, or any other purpose beyond that of your primary calendar. To create an additional or secondary calendar, select, "Add other calendars" at the top of the other calendars list, and then select, "Create new calendar." Give the calendar a name, optionally a description, and set the default time zone for events. Then select, "Create Calendar" to add it. When the calendar is added, it will appear in your, "My Calendars" list beneath your primary calendar. You can then modify the settings for it, and add collaborators and viewers. After you've created your additional calendar, you should ensure that you set the permissions correctly. Calendars you've added to your lists, that is, the calendars other than your primary calendar tasks and reminders, can be removed when you no longer need to view or interact with them. Select, "Unsubscribe" to remove a calendar. This won't remove the calendar from any other Google Calendar user, even if you created it. Alternatively, you can just hide the calendar from your view without unsubscribing from it, by deselecting the check box to the left of the calendar name. Or select, "Hide from list" from the calendar options pop-up to stop viewing it. To view it in your list again, open Google Calendar settings and select, "Showing calendar list," next to the calendar name.
