Hello People,

Right at this moment i working on an astrology program for on the internet. Lately i got contacted by a WvA astrologer(A dutch work community for astrologers) which has a very unusual approach to Astrology. For example they use hypothetical planets named Hermes, Demeter and Persephone. They also seem to use a unique house system called APC.

Anyway, my point is that i am trying to intergrate this hypothetical planets and house system. I already found the house tables and the ephemeride that is used by this group for the hypothetical planets. But as you can already guess, it isn't easy how to find out how to calculate the location of this planets or to calculate there house system.

The problem is this, the ephemeris with the hypothetical planets is not day based, but gives the position per month. To make it more clear, i will add the planet position for June 1984 from the ephemeris.

1984 positions:
1 Jan 27 vi 23 R
2 Feb 27 vi 15 R
3 Mar 26 vi 59 R
4 apr 26 vi 39 R
5 May 26 vi 22
6 June 26 vi 12
7 July 26 vi 14
8 Aug 26 vi 27
9 Sep 26 vi 48
10 Oct 27 vi 12
11 Nov 27 vi 34
12 Dec 27 vi 49

Let's take for example by birth date: 23-06-1984 UT: 05:51 Long: 06E27 52N22. I know i have to interpolate between 26 vi 12 and 26 vi 14, but how do i do this?

Greets,
Arjan.
