In that case I suggest to use the series 0, +/- 11* 29', +/- 20* 20', +/- 23* 27' for these lines. I myself often use 0, 11.5, 20 and 23.44 degrees. Thus calculte the lines as declination lines, not as lines of date. If you want to label them with our date then use 20, 21, 22, 23, just what's needed for that month. It is always an average.
