# EncodeDateMonthWeek

**EncodeDateMonthWeek** expands upon the function **EncodeDateWeek**.

This function returns a **TDateTime** that represents a specified day ADayOfWeek, of a specified week AWeekOfMonth, in a specified month **AMonth**, in a specified year **AYear**.

The time portion of the return value is 00:00:00 - midnight at the start of the specified day **ADayOfWeek**.

The definitions for **AWeekOfMonth** and **ADayOfWeek** follow the ISO 8601 standard.

* **AYear** is the year which can be any value from 1 through 9999 inclusive.

* **AMonth** can be any month value from 1 through to 12 inclusive.

* **AWeekOfMonth** is the week within **AMonth**, where 1 is the first week that includes four or more days.

  * If the first calendar day of the month is a Friday, Saturday, or Sunday, then those three days must be expressed using **AMonth** set to the previous month, and **AWeekOfMonth** must be set to the number of weeks in the previous month.
  * Similarly, if the last calendar day of the month is a Monday, Tuesday, or Wednesday, then those three days are expressed with **AMonth** set to the following month and **AWeekOfMonth** is set to 1.

* **ADayOfWeek** is the day of the week, where 1 is Monday, 2 is Tuesday e.t.c., with 7 representing Sunday.

If any of the specified parameters are not within range, **EncodeDateMonthWeek** will raise an error.
