All Implemented Interfaces:

Serializable, Comparable<ReadablePartial>, ReadablePartial
```
public final class MonthDay
extends BasePartial
implements ReadablePartial, Serializable
```
MonthDay is an immutable partial supporting the monthOfYear and dayOfMonth fields.
NOTE: This class only supports the two fields listed above. It is impossible to query any other fields, such as dayOfWeek or centuryOfEra.
Calculations on MonthDay are performed using a Chronology. This chronology is set to be in the UTC time zone for all calculations.
One use case for this class is to store a birthday without the year (to avoid storing the age of the person). This class can be used as the gMonthDay type in XML Schema.
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()
MonthDay is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

  - fromCalendarFields
```
public static MonthDay fromCalendarFields(Calendar calendar)
```
    Constructs a MonthDay from a java.util.Calendar using exactly the same field values avoiding any time zone effects.
    Each field is queried from the Calendar and assigned to the MonthDay.
    This factory method ignores the type of the calendar and always creates a MonthDay with ISO chronology. It is expected that you will only pass in instances of GregorianCalendar however this is not validated.
    
    Parameters:
    
    calendar - the Calendar to extract fields from
    
    Returns:
    
    the created MonthDay, never null
    
    Throws:
    
    IllegalArgumentException - if the calendar is null
    
    IllegalArgumentException - if the monthOfYear or dayOfMonth is invalid for the ISO chronology
  - fromDateFields
```
public static MonthDay fromDateFields(Date date)
```
    Constructs a MonthDay from a java.util.Date using exactly the same field values avoiding any time zone effects.
    Each field is queried from the Date and assigned to the MonthDay.
    This factory method always creates a MonthDay with ISO chronology.
    
    Parameters:
    
    date - the Date to extract fields from
    
    Returns:
    
    the created MonthDay, never null
    
    Throws:
    
    IllegalArgumentException - if the calendar is null
    
    IllegalArgumentException - if the monthOfYear or dayOfMonth is invalid for the ISO chronology
  - size
```
public int size()
```
    Gets the number of fields in this partial, which is two. The supported fields are MonthOfYear and DayOfMonth. Note that only these fields may be queried.
    
    Specified by:
    
    size in interface ReadablePartial
    
    Returns:
    
    the field count, two

                                 Chronology chrono)
```
    Gets the field for a specific index in the chronology specified.
    This method must not use any instance variables.
    
    Specified by:
    
    getField in class AbstractPartial
    
    Parameters:
    
    index - the index to retrieve

  - withChronologyRetainFields
```
public MonthDay withChronologyRetainFields(Chronology newChronology)
```
    Returns a copy of this month-day with the specified chronology. This instance is immutable and unaffected by this method call.
    This method retains the values of the fields, thus the result will typically refer to a different instant.
    The time zone of the specified chronology is ignored, as MonthDay operates without a time zone.
    
    Parameters:
    
    newChronology - the new chronology, null means ISO
    
    Returns:
    
    a copy of this month-day with a different chronology, never null
    
    Throws:
    
    IllegalArgumentException - if the values are invalid for the new chronology
  - withField
```
public MonthDay withField(DateTimeFieldType fieldType,
                          int value)
```
    Returns a copy of this month-day with the specified field set to a new value.
    For example, if the field type is dayOfMonth then the day would be changed in the returned instance.
    These three lines are equivalent:
```
 MonthDay updated = md.withField(DateTimeFieldType.dayOfMonth(), 6);
 MonthDay updated = md.dayOfMonth().setCopy(6);
 MonthDay updated = md.property(DateTimeFieldType.dayOfMonth()).setCopy(6);
 
```
    Parameters:
    
    fieldType - the field type to set, not null
    
    value - the value to set
    
    Returns:
    
    a copy of this instance with the field set, never null
    
    Throws:
    
    IllegalArgumentException - if the value is null or invalid
  - withFieldAdded
```
public MonthDay withFieldAdded(DurationFieldType fieldType,
                               int amount)
```
    Returns a copy of this month-day with the value of the specified field increased.
    If the addition is zero, then this is returned.
    These three lines are equivalent:
```
 MonthDay added = md.withFieldAdded(DurationFieldType.days(), 6);
 MonthDay added = md.plusDays(6);
 MonthDay added = md.dayOfMonth().addToCopy(6);
 
```
    Parameters:
    
    fieldType - the field type to add to, not null
    
    amount - the amount to add
    
    Returns:
    
    a copy of this instance with the field updated, never null
    
    Throws:
    
    IllegalArgumentException - if the value is null or invalid
    
    ArithmeticException - if the new date-time exceeds the capacity
  - withPeriodAdded
```
public MonthDay withPeriodAdded(ReadablePeriod period,
                                int scalar)
```
    Returns a copy of this month-day with the specified period added.
    If the addition is zero, then this is returned. Fields in the period that aren't present in the partial are ignored.
    This method is typically used to add multiple copies of complex period instances. Adding one field is best achieved using methods like withFieldAdded(DurationFieldType, int) or plusMonths(int).
    
    Parameters:
    
    period - the period to add to this one, null means zero
    
    scalar - the amount of times to add, such as -1 to subtract once
    
    Returns:
    
    a copy of this instance with the period added, never null
    
    Throws:
    
    ArithmeticException - if the new date-time exceeds the capacity
  - plus
```
public MonthDay plus(ReadablePeriod period)
```
    Returns a copy of this month-day with the specified period added.
    If the amount is zero or null, then this is returned.
    This method is typically used to add complex period instances. Adding one field is best achieved using methods like plusMonths(int).
    
    Parameters:
    
    period - the duration to add to this one, null means zero
    
    Returns:
    
    a copy of this instance with the period added, never null
    
    Throws:
    
    ArithmeticException - if the new month-day exceeds the capacity
  - plusMonths
```
public MonthDay plusMonths(int months)
```
    Returns a copy of this month-day plus the specified number of months.
    This month-day instance is immutable and unaffected by this method call. The month will wrap at the end of the year from December to January. The day will be adjusted to the last valid value if necessary.
    The following three lines are identical in effect:
```
 MonthDay added = md.plusMonths(6);
 MonthDay added = md.plus(Period.months(6));
 MonthDay added = md.withFieldAdded(DurationFieldType.months(), 6);
 
```
    Parameters:
    
    months - the amount of months to add, may be negative

```
public MonthDay minus(ReadablePeriod period)
```
    Returns a copy of this month-day with the specified period taken away.

    This method is typically used to subtract complex period instances. Subtracting one field is best achieved using methods like minusMonths(int).
    
    Parameters:
    
    period - the period to reduce this instant by
    
    Returns:
    
    a copy of this instance with the period taken away, never null

    This MonthDay instance is immutable and unaffected by this method call. The month will wrap at the end of the year from January to December. The day will be adjusted to the last valid value if necessary.
    The following three lines are identical in effect:
```
