Strictly biblical, the age of the prophets has ended. Supposedly the last prophet ended with the old testaments and we're currently living somewhere in Revelations. Here's an interesting fact though, did you know, when the book of Revelations was found, many considered not putting it in with the rest of the New Testament Books.
If your speaking of prophets in general, including those found in other religion and Christians like Mormons then supposedly a ton said they were around during the American Industrial Revolution and around the time of the Great Depression.
