How much time has passed in-universe in Detective Conan?


_Detective Conan_ is a notoriously long-running series -- it's been running
for like fifteen years, and hundreds of cases have been solved. Conan has made
friends, received upgraded technology over time (cell phones!), and has
generally "kept up" with its audience.

Yet, logically, time in-universe _must_ have passed, and Shinichi's continued
absence should be more notable than it is if he's been gone for more than a
year.

How much time has passed, currently, in the _Meitantei Conan_ universe?




Technically the story plays out in real time, but realistically it is at the
whim of the author.

Assuming the cases appear in chronological order. You'll notice that none of
the characters ever age or even graduate. There are many discrepancies the
Eisuke/Kir Arc alone has some serious and problematic time discrepancies. It
starts with the Nail and Snake Arc which took place a week or so after New
Years and then continues to some cases later in the Clash of Red and Black arc
which climaxing in a _certain_ person's death. Eisuke vanished around 18th to
19th of December... so chronologically speaking a year should have passed...
but did it? Ask Gosho Aoyama.
