Talk:Halloween 2019 Event (US)/@comment-26895338-20191019002028

The Last Encore Campaign ends on the 24th at 20:59 PDT, and the original file name for the banner image was called event_20191107_teaser.png. Based on this information I concluded that the duration date is what's listed above. I could be wrong but it should give a rough idea on when and how long the event will be.
