1) Could you please explain this one year thing a bit further- I was working initially and kept a khums date to pay khums on my salary but for things that I used to buy , I used to catch a year from the date I had bought those things:

For example I used to pay khums on my bank balance every year on 30th june but if I bought something on 2nd July I used to catch 1 year from 2nd July to use those things-

2) Also I am not working now so for things I have bought now – do I fix a specific khums date or just catch 1 year from the date of purchase

1) What you were doing is not correct according to the fatwa of S. Sistani.

2) Yes. Now you can do so.
