Your daily usage is calculated from the time you start your trip, to when your trip ends.

Please note that the usage is calculated based on the day that you end your trip, not the day you start your trip. This means that if for example, you start your trip at 10:00 AM and end it at 11:00 AM, but your pass expires at 10:30 AM, then that full trip will be charged at standard rate instead of being covered by the pass.
