A year-month in the ISO-8601 calendar system, such as 2007-12.
YearMonth is an immutable date-time object that represents the combination
of a year and month. Any field that can be derived from a year and month, such as
quarter-of-year, can be obtained.
This class does not store or represent a day, time or time-zone.
For example, the value "October 2007" can be stored in a YearMonth.
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.
