# WeekOfTheMonth

Extract the week of the month (and optionally month and year) from a TDateTime value

## Declaration

Source position: dateutil.inc line 202

`function WeekOfTheMonth(`
`const AValue: TDateTime`
`):Word; overload; function WeekOfTheMonth(`
`const AValue: TDateTime;`
`out AYear: Word;`
`out AMonth: Word`
`):Word; overload;`

## Arguments

`AValue` |  | TDateTime value of which to calculate the week, month and year.

## Function result

Week of the month

## Arguments

`AValue` |  | TDateTime value of which to calculate the week, month and year.
`AYear` |  | Year part of AValue
`AMonth` |  | Month part of AValue

## Description

WeekOfTheMonth extracts the week of the month from Avalue and returns it, and optionally returns the year and month as well (in AYear, AMonth respectively).

Remark: | Note that weeks are numbered from 1 using the ISO 8601 standard, and the day of the week as well. This means that the year and month may not be the same as the year part of the date, since the week may start in the previous year as the first week of the year is the week with at least 4 days in it.
