A great way to save time when sending a calendar invitation is by creating an event within a new Gmail message. For example, if you are sending some one (or several people) a message about an upcoming event, you can create an invitation within that new message.

This will automatically add the recipients of the message to the invitation, name the event the title of the message and add it your calendar.

Here are the simple steps:

1. Click Compose to open a new email.
2. Hover over the + icon at the bottom of the email window.
3. Click the Calendar icon.
4. Edit and add event details as desired.
5. Click Insert Invitation.
