* indicates the first Sunday in the {@code startMonth}. A {@code startDay} of -1 likewise
* indicates the last Sunday. However, by using negative or zero values for
* certain parameters, other types of rules can be specified.
* <p>
* Day of month: To specify an exact day of the month, such as March 1, set
* {@code startDayOfWeek} to zero.
* <p>
* Day of week after day of month: To specify the first day of the week
* occurring on or after an exact day of the month, make the day of the week
* negative. For example, if {@code startDay} is 5 and {@code startDayOfWeek} is {@code -MONDAY},
* this indicates the first Monday on or after the 5th day of the
* {@code startMonth}.
* <p>
* Day of week before day of month: To specify the last day of the week
* occurring on or before an exact day of the month, make the day of the
* week and the day of the month negative. For example, if {@code startDay} is {@code -21}
* and {@code startDayOfWeek} is {@code -WEDNESDAY}, this indicates the last Wednesday on or
* before the 21st of the {@code startMonth}.
