The chronologies are as determined by:

What was the month?
The sixth from the first.

which does NOT appear in the Strand edition (nor in American editions), however, the fact that the sun is due west (if one has an interior stone-flagged passage) when Holmes finishes pacing out the Ritual (soon after the tangent of the sun's angle was 2/3) demands a date for which the time from such a solar altitude to the time when the sun is due west is short (a date in high summer) and the discovery of the conical depression left by Brunton demands a date for which the solar Declination does not change too rapidly (a date near the solstice). Merrill (in "Holmes and Brunton: Civil Engineers," "The Case of the Missing Calendar," and "Hurlstone Revisited" (in the Baker Street Journal) argues against the conical depression (but accepts it) and accepts Zeisler's analysis (for the most part) of the couplet. As the couplet does not appear in the Strand, and there are other interpretations of it, I feel that the short time demanded, and a better analysis of the conical depression, DOES permit accepting the conical depression and an interior passage, at least for dates near the solstice (such as Christ's and mine).
