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 dates the reopening exactly: "Noma reopened on 15 February 2018 after a year hiatus", following Redzepi's plan to "close Noma after 31 December 2016 and reopen it in 2017 as an urban farm near Copenhagen".
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.
