Federation Day is a day of celebration commemorating the founding of the United Federation of Planets.

A card game called "Federation Day" poker existed in the 24th century, in which "2"s, "aces", and "6"s were wild, since the Federation was founded in 2161.

Deanna Troi suggested playing this game to the rest of the senior staff members of the USS Enterprise-D in 2368, however, Worf found it difficult to ascertain exactly what he had in his hand with so many wild cards. (TNG: "The Outcast")
