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.
NVIDIA's[2][3][5] poster call says "NVIDIA GTC is returning to San Jose, CA on March 15–18, 2027" and that "The event will take place between Sunday, March 14 and Thursday, March 18", so the pin spans 14-18 March (the GTC page itself says "NVIDIA GTC 2027 March 15–18"); no venue is named for 2027, so the pin sits at the McEnery Convention Center, GTC San Jose's venue in 2026.

NVIDIA's[1][2][5] San Jose venue page, still for the 2026 edition: "Experience GTC at the San Jose Convention Center", the San Jose McEnery Convention Center at 150 West San Carlos Street - the basis for placing the 2027 pin there.

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.
