Kinema Junpo , commonly called Kinejun (キネ旬), is Japan's oldest film magazine and began publication in July 1919. It was first published three times a month, using the Japanese Jun (旬) system of dividing months into three parts, but the postwar Kinema Junpō has been published twice a month.

Japanese calendar types have included a range of official and unofficial systems. At present, Japan uses the Gregorian calendar together with year designations stating the year of the reign of the current Emperor. The written form starts with the year, then the month and finally the day, coinciding with the ISO 8601 standard.
