businessYearEnd(X, [endingMonth=12], [offset], [n=1])

X is a scalar/vector of data type DATE, DATEHOUR, DATETIME, TIMESTAMP or NANOTIMESTAMP.

endingMonth is an integer between 1 and 12 indicating a month. The default value is 12.

offset (optional) is a scalar of the same data type as X, It must be no greater than the minimum value of X. The default value is the minimum value of X.

n (optional) is a positive integer. The default value is 1.

Return the last business day (Monday to Friday) of the year that X belongs to and that ends in the month of endingMonth.

If parameter offset is specified, the result is updated every n years. Parameter offset works only if parameter n>1.
