Wikipedia:Almanac

According to Wikipedia:Five pillars: "Wikipedia is an encyclopedia: It combines many features of general and specialized encyclopedias, almanacs, and gazetteers."

As the world's most extensive encyclopedia, Wikipedia goes far beyond the scope of an almanac. But it may contain any or all of the information you might find in an almanac, and then some. So, Wikipedia is not exclusively an almanac, but it may contain data formatted in almanac style.

Cf. WP:What Wikipedia is not#Wikipedia is not an indiscriminate collection of information (a policy that forbids excessive listings of statistics) and WP:Manual of Style/Trivia sections.
