This list hasn't been updated in like half a year or more, so I wouldn't be surprised that it's lacking several stories.

ME 7-9 were re-published as the Progressive series (Concerto will be published in December as Volume 2 of the series), so there isn't much point in dating these MEs, as their dates will be the same as the Progressive ones.

ME 1 should be 6-7th March 2024 (according to the anime at least), so after Black Swordsman, but before Murder Case.

ME 2 is a collection of character design art and the stats and skills of the players, so it doesn't really have a date.

ME 3 seems to be dated as "8-18th May 2026" (originally 8-18th May 2016 in the web version, 10 years are added in the published version). So, after Mother's Rosario, but before Alicization.
