I think time isn't an important element in DC because there is too much of plot for a shorter period of time. If they'd all get older they'd change as well...meaning as they will change school.....and such and their normal life as getting older isn't the focus Aoyama-sensei wants it to be........I guess....
I don't think they age either. References to age and birthday are usually dismissed by the other characters, and seem to always get forgotten.
I think that in the story Conan has aged least 2 years, because in one of the black organization cases he mentioned how it had been two years since the Tequila bombing case
haha but he still get the same class room after two years. is conan a moron who isn't good enough to pass the exam haha another mistake in school life manga
There was two Valentine's days in the anime, but only one in the manga.
And the seasons actually correspond to what season it was when they were made, so in the actual story it's only been a few months? But definately not a year
I still want to see something about Ran's birthday...
It hasn't been a year even though that doesn't make much sense:
In movie one, there was Shinichi's birthday, which is May 4 but in movie ten (i think - it's the one with the amusement park) They said something about something happening a month ago on April 4 and in movie 3, i think (not sure) they said the one girl's birthday was coming up and her b-day was on May 3 while the other girl was May 5 -- so...
Just try to ignore that...
