/**
* YearMonthDay is an immutable partial supporting the year, monthOfYear
* and dayOfMonth fields.
*
* NOTE: This class only supports the three fields listed above. Thus, you
* cannot query the dayOfWeek or centuryOfEra fields for example.
* The new LocalDate class removes this restriction.
*
* Calculations on YearMonthDay are performed using a {@link Chronology}.
* This chronology is set to be in the UTC time zone for all calculations.
*
* Each individual field can be queried in two ways:
*
* getMonthOfYear()
* monthOfYear().get()
*
* The second technique also provides access to other useful methods on the
* field:
*
* - numeric value -
monthOfYear().get()
* - text value -
monthOfYear().getAsText()
* - short text value -
monthOfYear().getAsShortText()
* - maximum/minimum values -
monthOfYear().getMaximumValue()
* - add/subtract -
monthOfYear().addToCopy()
* - set -
monthOfYear().setCopy()
*
*
* YearMonthDay is thread-safe and immutable, provided that the Chronology is as well.
* All standard Chronology classes supplied are thread-safe and immutable.
*
* @author Stephen Colebourne
* @since 1.0
* @deprecated Use LocalDate which has a much better internal implementation and
* has been available since 1.3
