Examples of com.google.ical.values.WeekdayNum

com.google.ical.values.WeekdayNum
represents a day of the week in a month or year such as the third monday of the month. A negative num indicates it counts from the end of the month or year.
Each BYDAY value can also be preceded by a positive (+n) or negative (-n) integer. If present, this indicates the nth occurrence of the specific day within the MONTHLY or YEARLY RRULE. For example, within a MONTHLY rule, +1MO (or simply 1MO) represents the first Monday within the month, whereas -1MO represents the last Monday of the month. If an integer modifier is not present, it means all days of this type within the specified frequency. For example, within a MONTHLY rule, MO represents all Mondays within the month.
