Represents a complete day using the Gregorian calendar.
This class is useful for indexing daily-granularity data or representing time periods that cover an entire day in local time somewhere. The major purpose of this class is "type safety", to prevent time-of-day values from sneaking in to data sets that should be daily only. As a secondary benefit, this uses less memory than datetimes.
The underlying datenum values that represent the days. The datenums are at the midnight that is at the start of the day it represents.
These are doubles, but they are restricted to be integer-valued, so they represent complete days, with no time-of-day component.
