The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Confirmed: Comic-Con's[2][6] own site gives "Comic-Con 2026, July 23–26 at the San Diego Convention Center" with "Preview Night on Wednesday, July 22, 2026", and Times of San Diego[3][4][5] reports the mayor spoke "on the opening day of this year's event... Wednesday morning" (22 July), so the pin runs from Preview Night on Wednesday 22 July to the exclusive 27 July.
Added when correcting this pin: comic-con.org[1][6]: the show proper was 23-26 July, with Preview Night on Wednesday 22 July (6-9 p.m.). The pin keeps its 22-27 July span and now says the Wednesday was Preview Night everywhere.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
