Add To Calendar button/link with Posts

Hi:

Can WP out of the box, or is there a plugin, that will allow me to include an Add to Calendar button/link with Posts.

Some of my posts are not calendar events so I want to include this button/link selectively. I’m hoping users can simply click on the link/button to add the event to their Outlook/Google/iCAL calendar. I would of course need to input the event info. into a calendar dB prior to creating the link for the event, then I would add the shortcode to the post.

Thank you!
