just had an Advanced Feng Shui seminar in which (amongst other things, calculating yearly and monthly stars was taught. Otherwise, one can sign up for the yearly/monthly charts from LSC and have them sent to them.
You can check on Marie's website under classes and seminars to see if she is hosting any on her own.
you can easily find monthly and annual star charts all over the internet feng shui sites. only problem is interpreting them. guess you'll have to figure out how to do that. =o)
