How long has it been?

Many analyses involve working with intervals or durations between two dates and times. Intervals are commonly taken between two fixed time points, such as when a project started and finished, but many also involve calculating intervals relative to the present time.

In this exercise, you'll be preparing the film data for analysis by calculating the date interval between each film's release and the present date. These date intervals will need to update in real-time as the present day changes.
