566 - If an event happens tomorrow but less than 24 hours away from us we still say that it happens  

567 tomorrow with no mention of the hour.  

568 - If an event happens tomorrow but more than 24 hours away from us, we'll count the number of days  

569 and hours in actual time.

572 relative to this morning and exclude all hours and minutes 

573 

574 On the other hand, if the current time of day is less or equal to the event's start of day we can produce  

575 the real difference in days and hours without the aforementioned simplifying language.
