firstHour

Determines the first hour that will be visible in the scroll pane.

<div class='spec' markdown='1'> Integer, *default*: `6` </div>

Values must be from 0-23, where 0=midnight, 1=1am, etc.

The user will be able to scroll upwards to see events before this time. If you want to prevent users from doing this, use the minTime option instead.
