It would be some logic using `range` in the query or a dynamic script. See ideas here: [How to filter date field by days and hours separately](https://discuss.elastic.co/t/how-to-filter-date-field-by-days-and-hours-separately/193946)

You could also consider using runtime fields ([Retrieve a runtime field | Elasticsearch Reference [7.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime-retrieving-fields.html)) to define day of the week or hour of day (or both) and then filter your query on that
