You can get todays day time and date using this code <?php echo date("d")." "; echo date("m")." "; echo date("Y")." "; echo date("h:i:s A"); ECHO ' <br/>'; echo jddayofweek ( cal_to_jd(CAL_GREGORIAN, date("m"),date("d"), date("Y")) , 1 ); ?>

Be aware that date() and mktime() only work as long as you move within the UNIX era (1970 - 2038 / 0x0 - 0x7FFFFFFF in seconds). Outside that era those functions are only generating errors. In other words: mktime(0, 0, 0, 12, 31, 1969) *DOES NOT* work (and so doesn't date() fed with with mktime()'s result from above). But cal_to_jd(CAL_GREGORIAN, 12, 11, 1969) *DOES WORK*. And please note that the calendar-extension's functions arguments follow the US date order: month - day - year.
