Which New Year's Eve event in New York City was canceled in 1942 and 1943 because of wartime blackout rules?

The Times Square ball drop was canceled in 1942 and 1943 because of wartime blackout rules.

During World War II, New York City limited visible lights to reduce the chance that enemy forces could use the coastline and illuminated cities as navigation references. Because the Times Square Ball depended on bright illumination, officials did not lower it at midnight during those two New Year's celebrations.

The crowds did not disappear entirely. People still gathered in Times Square, but the usual glowing descent was replaced by a period of silence followed by ringing church bells. The interruption was a reminder that a highly visible public celebration was subject to national security restrictions.

The ball drop resumed after the wartime blackout period. This pause is sometimes omitted from simplified histories that describe the tradition as uninterrupted since 1907. It also differs from temporary modern changes caused by weather, public-health restrictions, or technical arrangements; the 1942 and 1943 cancellations were specifically tied to World War II blackout conditions.
