$cal = new IntlGregorianCalendar(2013, 0 /* January */, 2);
var_dump(IntlDateFormatter::formatObject($cal, 'cccc')); // Wednesday

var_dump($cal->getMinimalDaysInFirstWeek(), // 1
$cal->getFirstDayofWeek()); // 1 (Sunday)

// Week 1 of 2013
var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

$cal->setMinimalDaysInFirstWeek(4);

var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

$cal->setMinimalDaysInFirstWeek(6);
// Week 53 of 2012
