You can take a column out of multi-dimensional array on which you want to do aggregation / count.

<?php

$array = [['name' => 'foo', 'date' => '2017-11-28'], ['name' => 'bar', 'date' => '2017-11-29'], ['name' => 'baz', 'date' => '2017-11-28']];

$dates = array_column($array, 'date'); // here 1st param is the array

This will give you

Array
(
    [0] => 2017-11-28
    [1] => 2017-11-29
    [2] => 2017-11-28
)

Now you can call array_count_values like:

print_r(array_count_values($dates));

Array
(
    [2017-11-28] => 2
    [2017-11-29] => 1
)
