I think you could say, well into the 20th century, for Latin in school education. And also I have heard that there was considerable amounts of literature being produced in Latin even into the 18th and 19th centuries, so much for being a dead language, if new serious literature is being produced in it even 1000s of years after its heyday. May be it is true for Classical Greek as well. The famous orthodox hymn Agni Parthene was written only in the late 19th century.
