In this tip for the iPhone, I show you how you can show the week numbers in the Calendar app on the iPhone. When this is enabled, you will see the week numbers on the left side of your calendar while viewing it as a month.

This also works for the iPad! You use the same technique through the settings app. With the iPad, there is an added bonus, you can see the week numbers while viewing your calendar in week view as well.
