Source:One of the hashtags includes the date "June 22 2015." It was because of this tag that this Tweet drew lots of attention from fans both Japan-based and internationally, claiming that Ogata officially dated the first episode—"Angel Attack"— as being set on June 22, 2015. There had been no indication as to when precisely the episode took place other than in the year 2015.
However, King Records—the general distributor of Evangelion music—released a statement via a phone interview with Huffington Post that June 22 is not the official date that the episode takes place. King Records stated that "[Ogata-san's] remark was simply an unofficial liberty she took as a performer."
