While you might not be able to recall anything from your own undergraduate commencement speech, chances are you've been inspired by some of the most memorable ones. Now that May has arrived, you can expect a few more for that list. 

Commencement speeches are targeted toward a very specific audience of people who are on the verge of starting their careers, but the best speakers tend to offer age-agonistic advice. 

For example, Steve Jobs: "Your time is limited, so don't waste it living someone else's life." And Ellen DeGeneres: "Follow your passion, stay true to yourself, never follow someone else's path. Unless you're in the woods and you're lost and you see a path. Then, by all means, you should follow that."

Below are the dates of upcoming talks from notable speakers. Mark your calendars, and stay tuned for Inc.'s coverage of some of the best ones.
