    Returns whether either the obejctʼs current time or the provided timestamp occur during a weekend in this objectʼs calendar system.

    This function requires ICU 4.4 or later.

    参数

    $cal

    The IntlCalendar resource.

    $date

    An optional timestamp representing the number of milliseconds since the epoch, excluding leap seconds. If NULL, this objectʼs current time is used instead.

    返回值
