Description

EncodeDayOfWeekInMonth returns a TDateTime for the date specified by the AYear, AMonth, ANthDayOfWeek, and ADayOfWeek parameters. The time portion of the return value is 0 (Midnight at the start of the specified day).

AYear is the year. It can be any value between 1 and 9999 (inclusive).

AMonth is the month. It can be any value between 1 and 12 (inclusive).

ANthDayOfWeek indicates the occurrence for the day of the week represented by ADayOfWeek. It can be any value between 1 and 5 (inclusive), as long as this value specifies a valid date. For example, if a month does not include 5 Mondays, setting ANthDayOfWeek to 5 and ADayOfWeek to 1 causes EncodeDayOfWeekInMonth to raise an exception.

ADayOfWeek is the day of the week, where 1 Monday and 7 is Sunday.

Note: The definition for ADayOfWeek follows the ISO 8601 standard.

Tip: To make the ADayOfWeek value more readable, use the Day of week constants.
