### Astrology: Calculating the House Cusps.

Example: Mary was born  7 May 1982 at 11 hours 17 minutes AM, New Berlin, New York, USA. The longitude is 75 degrees, 20 minutes west of Greenwich. And the latitude is 42 degrees 37 minutes North of the equator.

Her LST is 1 hour 16 minutes 13 seconds.

Having calculated the sidereal time and other factors previously, we can go on to calculate the house cusps for the Placidean system. All we need to calculate are four cusps, because we have already calculated the Ascendant and the MC and the other cusps are opposite these ones.

We can proceed as with the ascendant and we can use the same factors as before. The factor for latitude is 0.6167 and the factor for time is 0.0542..

My results are as follows:

 Time 1 hour 16 Latitude 11 12 2 3 42 degrees 2731 356 2452 1924 43 degrees 2743 427 257 1927 42 degrees 37 2738 415 2501 1926

 Time 1 hour 20 Latitude 11 12 2 3 42 degrees 2834 449 2543 2022 43 degrees 2848 520 2557 2024 42 degrees 37 2843 508 2551 2023 Values 2742 417 2504 1929

 Cusp Values 11 12 2 3 2742 417 2504 1929 5 6 8 9 2742 417 2504 1929

The cusps 5,6,8 and 9 are obtained by reversing the sign on the other cusps. The results are accurate to an arcminute.
