Google is showing the Wrong Date for our Holiday.

Friday, December 16 is Free Shipping Day. However, Google says it's actually 2 days later. Does anybody know how we can get that changed?

Hi Luke,

You or me or any body except from Google cannot fix that. Do one thing take the screenshot and tweet to @googlewmc hope you will get some reply.

Thanks

Yeah, unfortunately, that's core Knowledge Graph (not a Featured Snippet), so it's coming from a partnered data source. I'm not sure where they're pulling this from, though, as the Wikidata/Wikipedia entries seem correct:

https://en.wikipedia.org/wiki/Free_Shipping_Day

There's not even a "report" option on this one, so I'm afraid Alick300 is right - you're going to have to contact Google directly, I'll ask around on Twitter, but Google isn't transparent at all about these data sources.
