	// note we are comparing the first element of each array
	if ( $a[0] < $b[0] ) {
		return -1;
	if ( $a[0] > $b[0] ) {

Initial Description
For more information, see, under usort

It works with dates

Replace 0 for the array's key you want to sort. For example, if you have a start_date array key you would like to compare, then you would replace 0 for start_date.

If you want to do a reverse sort, just switch the -1 and 1.
