Timeline-wise, this episode is one of the few points in the series which can actually be firmly dated: when Misato is marking off on a calendar the day that the final battle against Israfel will take place, we see that it occurs on Friday the 11th. In 2015, Friday will fall on the 11th only in either September or December. It is not at first clear which month it is, because the bottom of the calendar cannot be seen (December has 31 days, September only 30). However, December can be ruled out, because in later episodes a period of time longer than one month passes, but it is still "2015". For example, over 30 days pass in Episode 20 alone, and if Episode 09 took place on December 11th that would push the following episodes into 2016. However, computer displays of dates after Episode 20 (i.e. on Maya Ibuki's laptop during The End of Evangelion, etc.) still say that it is "2015". Thus, the final battle against Israfel takes place on September 11th, 2015.
Может, график дежурств по классу, а Танака - это один из школьников?
Позже проверю по иероглифам.
