I was using `IntlGregorianCalendar` because it offered a nice way to get the week number of the year as an integer. This differs from `DateTime`; `DateTime` gives you the week number of the year as an string.

<?php

$dateTime
= new DateTime('21-09-2020 09:00:00');
echo
$dateTime->format("W"); // string '39'

$intlCalendar = IntlCalendar::fromDateTime ('21-09-2020 09:00:00');
echo
$intlCalendar->get(IntlCalendar::FIELD_WEEK_OF_YEAR); // integer 39
