I am just studying for the FAA IR, Jeppesen IR/Commercial Manual states that :
"Within the preceeding 6 calender months you must have intercepted and tracked courses throught the use of navigational systems, performed holding procedures, and flown at least 6 instrument approaches. these instrument procedures must be accoplished under actual or simulated instrument conditions in flight, in a flgiht simujlator or a flight training device"
Basically if you dont do the 6 with 6 months you are no longer Instrument current, you then have a further 6 months to meet the requiremnts or you have to take an instrument proficiency check.
Its worth knowing that the approachs can be done in a sim - bit cheaper!
