1866년(고종 3) 관상감에서 간행한 책력冊曆에 병인박해와 병인양요의 정황을 일지 형식으로 기록했다. 병인박해 증언록의 내용과 거의 일치한다.

In 1866 (the third year of King Gojong’s reign), the circumstances surrounding the Byeongin Persecution and the French expedition to Korea, known as Byeongin Yangyo, were documented in the form of a daily log within an almanac published by the Office of Meteorology and Astronomy (Gwansanggam). The recorded content closely mirrors the testimonies of the Byeongin Persecution.
