This graph looks pretty even, so I'm going to conclude the same thing everyone else does: babies don't care anything about what the moon's doing, they come when they're ready to be born.
// Start with the date you're learning about ($timestamp) $synmonth = 29.53059; // Days in a synodic lunar month $oneday = 24*60*60; // Seconds in a day $firstnew = mktime(12,0,0,1,26,1971); // We happen to know there was a new moon on 26 Jan 1971 $timestamp = $timestamp-$firstnew; // Difference between our timestamp and the new moon $daysoff = round(fmod($timestamp,$synmonth*$oneday)/$oneday,0);
