Took this from the Internet :) Nice play of words :) Also answers your question ^_^ "In most cases, there is no difference at all. For example, there is no difference in the meaning of these sentences: I visit my mother often. I visit my mother frequently. In practice (American English), often is used much more frequently than frequently. Frequently is used much less often than often. I think that is because often is a shorter (easier) word and people think of it more frequently."

Very little difference. Both mean to occur repeatedly. In most conversations you can use either word.
