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.
The source gives the year only: "In 2010, Anand opened Gaggan in a 19th-century townhouse renovated to accommodate the restaurant." A year-only date sits on that year's last day.
The World's 50 Best publishes both the world and Asia rankings the pin cites for Gaggan.[1]
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.
