How the houses are counted
Houses here use whole-sign counting: your rising sign is the whole 1st house, the next sign the 2nd, and so on around the zodiac. Many astrologers use Placidus or another quadrant system instead, which can move a planet close to a sign boundary into the neighbouring house. Either way you need an accurate birth time, because the rising sign changes about every two hours.
