I had a Chinese teacher who told us that March 14th was White Valentine&#x27;s Day, when valentine&#x27;s gifts are reciprocated. A month after that, on April 14th, you have Black Valentine&#x27;s Day.<p>Those holidays are known to wikipedia, although it attributes &quot;White Day&quot; primarily to Japan and &quot;Black Day&quot; exclusively to Korea.<p>So the opposite of Valentine&#x27;s Day is already placed; April 14th. I don&#x27;t see why Western Forever Alone Day would need to be scheduled differently from Chinese Forever Alone Day -- the date was picked for being all ones. (And, I&#x27;m told, you can celebrate by eating 1-shaped Pocky.)
