I have posts with a meta start_date and a meta end_date, stored in timestamp format (I can change the format if necessary) I would like to return all posts that have a date in that month by giving a specific month.

For example, if I am looking for June 2019 and a post has a start_date from May 15, 2019 to June 3, 2019, this post should be returned.

How can I make this query?
