Google has started including dates for particular holidays and celebrations right on the search results page for certain queries. That includes some more obscure occasions, such as National Popcorn Day.
"This currently works for certain future and past national and religious holidays, internationally recognized days such as World AIDS Day, and designated days to celebrate fun things like popcorn and cookies in the U.S.," says Google software engineer intern Anis Abboud. "Speaking of which, it’s time to start looking for great cheesecake recipes, as National Cheesecake Day is just around the corner!"
"It can be difficult keeping track of the dates of national holidays when it’s hard enough to remember special anniversaries and loved ones’ birthdays," says Abboud.
I don't think it's been that hard to find these dates in the past, but this would make it at least one click easier.
I would not be surprised to see brands continue to manufacture new "holidays" based on the products that they sell. It will be interesting to see how Google keeps up this feature related to those.
