Code to compute the dates that match an iCal RRULE.

Code

function date_repeat_set_month_day($date_in, $day, $count = 1, $direction = '+') {
  if (is_object($date_in)) {

    // Reset to the start of the month.
    // We should be able to do this with date_date_set(), but
    // for some reason the date occasionally gets confused if run
    // through this function multiple times. It seems to work
    // reliably if we create a new object each time.
    $datetime = date_format($date_in, DATE_FORMAT_DATETIME);
    $datetime = substr_replace($datetime, '01', 8, 2);

      // For negative search, start from the end of the month.
      date_modify($date, '+1 month');
    }
    else {

      // For positive search, back up one day to get outside the
      // current month, so we can catch the first of the month.
      date_modify($date, '-1 day');
