Working days

Durations of workflow steps and due dates of tasks are counted in working days.

Option	Default	Purpose
$workingDays	[1, 2, 3, 4, 5]	ISO weekdays, 1 (Monday) to 7 (Sunday)
$holidayProvider	null	class implementing Anvil\Calendar\HolidayProvider
$holidayRegion	null	region passed to the provider
$closedDays	[]	further days without work: '12-24' every year or '2026-12-28' once

public array $workingDays       = [1, 2, 3, 4, 5];
public ?string $holidayProvider = \Anvil\Calendar\GermanHolidays::class;
public ?string $holidayRegion   = 'BW';                 // Baden-Württemberg
public array $closedDays        = ['12-24', '12-31'];

• GermanHolidays knows the public holidays of Germany and of every federal state: BW, BY, BE, BB, HB, HH, HE, MV, NI, NW, RP, SL, SN, ST, SH, TH. Without a region only the holidays of the whole country count.
• Other countries implement HolidayProvider (holidays(int $year) returning Y-m-d => name); the region is passed to its constructor.
• $holidayRegion can be set per environment: anvil.holidayRegion = BY.
• A changed calendar applies to new due dates; existing deadlines stay.
