It's an archaic term, which shouldn't really be used nowadays by anybody who knows what they're talking about. It started off in the 16th century as a linguistic term, used to describe a family of languages in Britain. The use of the word was expanded to include non-linguistic matters, pertaining to some similarities in culture and suchlike (which didn't necessarily overlap the linguistic centres) - particularly in the 19th and early 20th centuries. The notion of "Celtic" countries is a modern one, and largely has its roots in the practice of grouping together the places where these old Celtic languages were spoken. Contrary to what Victorian antiquarians asserted, there never was a race of Celts.
Just like "Viking", it is a horribly misused word (almost never used correctly), but due to its popularity it is extremely convenient. Everybody knows what you mean when you say it, even though it has no actual basis or merit.
