    One quibble with George Huxtable.  He wrote:

    The reason I chose May was because at the solstice the rate of change
    in declination, the first difference, is close to zero, so it doesn't
    matter what the second difference is.  In May, there is still a
    significant first difference, but the second difference is also
    becoming large, to reach maximum at the solstice.  The second
    difference was zero at the equinox.
