Biweekly

Schedule runs every 2 weeks on the given weekdays. The week of the schedule’s start date (or the optional anchor) is the first occurrence.

$schedule = Zap::for($doctor)
    ->named('Office Hours')
    ->availability();

// Bi-weekly (week of the start date by default, optional anchor)
$schedule->biweekly(['tuesday', 'thursday'])
    ->from('2025-01-07')
    ->to('2025-03-31');

Use from()/to() or forYear() and addPeriod() as needed, then save().

For intervals of 3 to 52 weeks, use the dynamic weekly methods: Every X weeks (everyThreeWeeks, everyFourWeeks, … everyFiftyTwoWeeks).
