Tochnaja data sobytij v lagere "Sovjonok" ili progulka s Violoj

For a long time, I was wondering what year the events of the game took place in the original script. I spent a long time digging through the Internet. I think I found it on Ychan that the date of the events was August 1989. Moreover, many disputed this date and suggested their own. In their disputes, the Ychans referred to the full moons to prove their own case. It was this clue that became decisive, and I had the idea to conduct an investigation. Having dug up the script from beginning to end, I found some clues that somehow hinted at the date of the events of the game. Fortunately, I had a special astronomical program for analyzing the full moons. Having compared all the data, I came to the conclusion about the exact date of the events.
