lweekdate

Date of last occurrence of weekday in month

Syntax

• LastDate = lweekdate(Weekday, Year, Month, NextDay)
  

Arguments

Weekday	Weekday whose date you seek. Enter as an integer from 1 through 7:
	1	Sunday
	2	Monday
	3	Tuesday
	4	Wednesday
	5	Thursday
	6	Friday
	7	Saturday
Year	Year. Enter as a four-digit integer.
Month	Month. Enter as an integer from 1 through 12.
NextDay	(Optional) Weekday that must occur after Weekday in the same week. Enter as an integer from 0 through 7, where 0 = ignore (default) and 1 through 7 are as for Weekday.

Any input can contain multiple values, but if so, all other inputs must contain the same number of values or a single value that applies to all. For example, if Year is a 1-by-n vector of integers, then Month must be a 1-by-n vector of integers or a single integer. LastDate is then a 1-by-n vector of date numbers.

Description

LastDate = lweekdate(Weekday, Year, Month, NextDay) returns the serial date number for the last occurrence of Weekday in the given year and month and in a week that also contains NextDay.

Use the function datestr to convert serial date numbers to formatted date strings.
