Garden Visit Duration

You have arrived at a garden that is open daily from \(08:00\) to \(20:00\). Given the current time in the format \(HH:MM\) (24-hour clock), determine the maximum number of minutes you are allowed to stay. Note that even if the garden is open, you cannot stay for more than 60 minutes, regardless of how much time remains before closing.

If you arrive before \(08:00\) or at/after \(20:00\), you cannot stay at all and the output should be 0.
