The sequence 04-02-17 is widely interpreted as a date. Given that JAV releases are often dated in the format, or the American MM-DD-YY format, this likely points to April 2, 2017 . Why is this date important? The original video was released on October 6, 2016. Therefore, 04-02-17 is not the production release date. Instead, it is most likely the date a particular subtitle file was created or uploaded by a user. In the subtitle database SubtitleNexus, for example, every subtitle entry includes a "Date" column that records when the subtitle file was uploaded. This date would be 04-02-17 or April 2, 2017 . nhdta-889-rm-javhd.today04-02-17 Min
