getMinimalDaysInFirstWeek()

Returns the minimal days required in the first week of the year.

Syntax

Numeric getMinimalDaysInFirstWeek()

Usage

For example, return the minimal days the first week of the year by calling:

Calendar.fromDate(Date.fromIsoValue(orderline.orders.orderdate.isoValue),"YYYY-MM-DD").getMinimalDaysInFirstWeek()

This example populates a Decimal Format Box.

If the first week is defined as one that contains the first day of the first month of a year, this method returns 1. If the minimal days required must be a full week, this method returns 7.

Calendar defines a locale-specific seven day week using two parameters: the first day of the week and the minimal days in first week (from 1 to 7). These numbers are taken from the locale resource data when a Calendar is constructed. They may also be specified explicitly through the methods for setting their values.

When setting or getting the WEEK_OF_MONTH or WEEK_OF_YEAR fields, Calendar must determine the first week of the month or year as a reference point. The first week of a month or year is defined as the earliest seven day period beginning on getFirstDayOfWeek() and containing at least getMinimalDaysInFirstWeek()days of that month or year. Weeks numbered -1 or 0 precede the first week; weeks numbered 2, or 3 follow it.
