Rahu dasa is in its last few months and will be over on June 18, 2014. This date could vary slightly depending on different schools of thought in Astrology. But your experiences show that we should take the above date as the beginning of a new Jupiter Dasa which is a Benefic for you as was Rahu Dasa.
