I am very new to the ordeal of incorporating citations into my work, but I'm working on a project for school, and in it, I'm using the APA 6th citation format. https://www.nationalgeographic.org/encyclopedia/core/
This is a source I used. I believe it falls under the category of "Website" (translated from Norwegian, I'm using a website that shows the different formats of citation for different text types). Now, the link provided is described by NatGeo as an encyclopedic entry, and no authors nor publication date is to be seen anywhere. I couldn't spot it at least. Now, the website I used said that the format of citation for "Websites" is like this:
Blah-blah-blah (National Geographic, 2009)
However, I can't find that date that I need to include at the end. Is there then an altenative format to use? Or am I just not looking properly for said date?
