Twelve by twelve

Your Sun is the half people quote back to you.

The other half is the Moon, and it is the one deciding whether you can rest. Twelve signs for each gives 144 pairs, and the pair is where the interesting part is — what you are building and what has to be in place before you can stop building are almost never the same thing. One page each.

Both placements come from the ephemeris, not from a table of birthdays. The Sun holds a sign for about a month; the Moon changes every two and a half days, so the hour matters on that half.
