DC's site has gone down the toilet. It used to be so easy to search on a release calendar and it seems like now they are intentionally making it difficult to use. Don't know if they don't have the resources to make it user friendly, or just don't care anymore.
Also, don't know if anyone noticed, but Stargirl might be slipping a week. It had been solicited and scheduled for a while for March 21, and most sites still show that date. But, League of Comics Geeks is showing March 28. They aren't infallible, but they are usually pretty accurate and earlier than most in updating their site.
