my round use to be a bit like this, in the end i printed 20 days worth of blank sheets off and numbered them 1 - 20 then marked each day with a village, ie st dennis, st stephen, then just fill each day up with jobs, till that day was finished then moved rest on to next day ie i got 2 streets in st dennis, that take 2 and half days, so they fill up day 1, 2, 3 then day 4 goes to st stephen, now i know where i am on any given day of the month, i found it easier to write it down before on i put it on a computer becasue i found it easier to work out and if i need to change any thing , just meant moving a bit of paper,
just go out and do the round to your new sheets, most custys wouldnt even notice the time difference
