I would like to back trade, but I find that if I use numbers to indicate the day(s) of PCFs - i.e., C435 - I don't know the date to go back to in order to check the chart (without counting backwards to Day 435).  And if I use a range of dates to check, say, MAs - i.e., C'1/23/10' back to C'1/2/10' consecutive - then I don't know if the dates hit holidays or weekends without manually matching up the days to dates - which could be very time consuming when working with sophisticated PCFs..

Is there any way to match up trading days to calendar days?

Thanks for your time.
