-/**
- * The Thai Buddhist calendar system.
- * <p>
- * This chronology defines the rules of the Thai Buddhist calendar system.
- * This calendar system is primarily used in Thailand.
- * Dates are aligned such that {@code 2484-01-01 (Buddhist)} is {@code 1941-01-01 (ISO)}.
- * <p>
- * The fields are defined as follows:
- * <p><ul>
- * <li>era - There are two eras, the current 'Buddhist' (ERA_BE) and the previous era (ERA_BEFORE_BE).
- * <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 plus 543.
- * <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 plus 543.
- * <li>month-of-year - The ThaiBuddhist month-of-year exactly matches ISO.
- * <li>day-of-month - The ThaiBuddhist day-of-month exactly matches ISO.
- * <li>day-of-year - The ThaiBuddhist day-of-year exactly matches ISO.
- * <li>leap-year - The ThaiBuddhist 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.
