Notice the time on the poster itself seems to be correct except that the New York UTC one needs to be (2:30AM UTC Oct 30)

The correct timing hence therefore is:
Halloween 2022 - EU - 8PM GMT+1 October 29
(7:00PM UTC Oct 29) (London)
Halloween 2022 - NA - 10:30PM EST October 29
(2:30AM UTC Oct 30) (New York)
