金曜13日の歴史：出典の重なりであり交通統計ではない

近代の英語慣用です。手術を日付迷信で延ばさないでください。

Modern English idiom

1307

The arrests are an event. A straight line from that Friday to today’s horror films is overclaim.

Split from calendar and 13

East Asia

Local taboos often centre on 4. Imported films overlay the image. Not statistics.
