-/**
- * The Minguo calendar system.
- * <p>
- * This chronology defines the rules of the Minguo calendar system.
- * This calendar system is primarily used in the Republic of China, often known as Taiwan.
- * Dates are aligned such that {@code 0001-01-01 (Minguo)} is {@code 1911-01-01 (ISO)}.
- * <p>
- * The fields are defined as follows:
- * <p><ul>
- * <li>era - There are two eras, the current 'Republic' (ERA_ROC) and the previous era (ERA_BEFORE_ROC).
- * <li>year-of-era - The year-of-era for the current era increases uniformly from the epoch at year one.
- * For the previous era the year increases from one as time goes backwards.
- * The value for the current era is equal to the ISO proleptic-year minus 1911.
- * <li>proleptic-year - The proleptic year is the same as the year-of-era for the
- * current era. For the previous era, years have zero, then negative values.
- * The value is equal to the ISO proleptic-year minus 1911.
- * <li>month-of-year - The Minguo month-of-year exactly matches ISO.
- * <li>day-of-month - The Minguo day-of-month exactly matches ISO.
- * <li>day-of-year - The Minguo day-of-year exactly matches ISO.
- * <li>leap-year - The Minguo leap-year pattern exactly matches ISO, such that the two calendars
- * are never out of step.
- * </ul><p>
- *
- * <h3>Specification for implementors</h3>
- * This class is immutable and thread-safe.
