How to export an event to Google, Hotmail, Outlook, or Yahoo! calendar

To export an existing event to another calendar account (e.g. to a Google calendar), you can simply open the "Edit Event" screen of that event and change the value of the "Calendar" field to the desired calendar account. This post walks you through the steps. It assumes that the Google Calendar account is not yet added on your iPhone: http://smallbusiness.chron.com/export-iphone-calendar-items-import-gmail-30346.html

The same steps can be applied to other calendar account types (e.g. Hotmail, Yahoo!, etc..).

Some background here: It is the "Calendar" of an event that determines which account the event is linked with.
