MonthWeekdayUtils class abstract final

Static (year, month)-keyed weekday-occurrence helpers, the no-seed counterpart to the DateTime.getNthWeekdayOfMonthInYear instance extension.

Calendar-construction code (DST rules, public-holiday tables) computes occurrences for an arbitrary year/month pair and has no seed DateTime to hang the instance method on; these statics take the year/month explicitly so no throwaway DateTime(year, month) is needed at every call site.

Static Methods

lastWeekdayOfMonth(int year, int month, int weekday) → DateTime

Returns the last weekday in month of year — always a real date, since every weekday occurs at least four times a month.

nthWeekdayOfMonth(int year, int month, int n, int weekday) → DateTime?

Returns the nth weekday in month of year, or null when that occurrence does not exist (e.g. a 5th Friday in a month with only four).
