+## WooCommerce REST API Updates
+
+### Update the `date_query` usage in the CRUD controller to be consistent, generating an array of queries.
+
+PR: https://github.com/woocommerce/woocommerce/pull/29909
+
+To test:
+1. From the WordPress general settings page (/wp-admin/options-general.php), set the timezone of your site to "UTC +4".
+2. Create a new order from WooCommerce > Orders > Add Order (/wp-admin/post-new.php?post_type=shop_order).
+3. Set the date created to 2021-05-14 @ 00:00.
+4. Create a REST API Key from WooCommerce > Settings > Advanced > REST API. Take note of the consumer key and secret.
+5. Make a request to the orders endpoint to verify that `post_date_gmt` is used. See example below. Replace [domain], [consumer_key], and [consumer_secret]:
+```
+curl "https://[domain]/wp-json/wc/v3/orders?dates_are_gmt=true&after=2021-05-13T19:00:00&before=2021-05-13T22:00:00&consumer_key=[consumer_key]&consumer_secret=[consumer_secret]"
+```
+6. Verify that the order you created in step 2 is included in the results.
