+/**
+ * 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.
