This module will make the date API available to other modules. Designed to provide a light but flexible assortment of functions and constants, with more functionality in additional files that are not loaded unless other modules specifically include them.

Code

function date_week_range($week, $year) {
  if (variable_get('date_api_use_iso8601', FALSE)) {
    return date_iso_week_range($week, $year);
  }
  $min_date = new DateObject($year . '-01-01 00:00:00');
  $min_date
    ->setTimezone(date_default_timezone_object());

  // move to the right week
  date_modify($min_date, '+' . strval(7 * ($week - 1)) . ' days');

  // move backwards to the first day of the week
  $first_day = variable_get('date_first_day', 1);
  $day_wday = date_format($min_date, 'w');
  date_modify($min_date, '-' . strval((7 + $day_wday - $first_day) % 7) . ' days');

  // move forwards to the last day of the week
  $max_date = clone $min_date;
  date_modify($max_date, '+7 days');
