The following review written by one of the Software Informer contributors applies to version 7.3
Astrology is the art of interpreting the positions of planets and stars, and their influence in human life. In India such art is based on the Vedas, which are the sacred texts of the Hindu religion.
This program features pre-calculated figures that can be interpreted by an experienced Vedic astrologer, thus saving users a lot of time. You only need to enter your birth data, such as date, place, hour, time zone and so on. The program will show the calculations and different kinds of tables with comprehensive data regarding the position of planets, houses, constellations and other elements. Please note that the program will not tell you your horoscope nor your fortune; it only features the calculations and tables that must be interpreted by a reputable Vedic astrologer. Nevertheless, the program's Help file features a comprehensive introduction to Vedic astrology that can allow you to better understand the subject.
If you are an astrologer or if you want to learn more about Vedic astrology using one of the most ancient and respected astrological systems, then don't miss this program, which is absolutely free.
There is a more recent version available for downloading at the developer's site.


  • Free.
  • The Help file is very comprehensive.


  • Very specialized. Not for the casual user.
  • Only Windows-compatible

What's new in version 7.5

Changes from 7.5 to 7.51:
(1) When SSS is selected as the siddhanta (planetary model) and some sunrise definitions are selected, JHora 7.5 freezes. This is fixed.
(2) In nakshatra dasas, an option is added to shift dasa lordships by any number of nakshatras. For example, one can start Vimsottari dasa from Ardra (instead of Krittika). Then Ardra (instead of Krittika) will give 6 years of Sun dasa, Punarvasu (instead of Rohini) will give 10 years Moon dasa, Pushyami (instead of Mrigasira) will give 7 years of Mars dasa, and so on. [This is recommended by "Lomasha Samhita" for some charts.]
(3) Vimsottari dasa can now be computed using complete anti-zodiacal reckoning (e.g. Rahu-centric theory).
(4) With the same calculation options, planetary longitudes with 7.5 were off from those with 7.4 by a few arc-sec. Values given by 7.4 were accurate and 7.5 drik siddhanta calculation of planets had a bug. This bug is fixed.
(5) Chara dasa, Yogardha dasa, Trikona dasa, Lagna Kendradi Rasi dasa and AK Kendradi Graha dasa can be calculated in divisional charts now.
(6) When SSS is selected (instead of drik siddhanta), no house division system other than "Equal house - 30 deg each" works in 7.5. It is fixed now and all house division systems will work. [The house system taught in a BPHS version saccording to Sri Vinay Jha is not included yet.]
(7) Option was added to the divisional chart calculation options to find divisional longitudes in D-30 by mapping each one degree in rasi to 30 degrees in D-30 or to map arcs (e.g. 5 deg or 8 deg arc) that go to the same sign in D-30 to 30 degrees *together* in D-30.
(8) Chandra Hari ayanamsa implementation is changed to place Shaula star (Lambda Scorpii) at 240 degrees of the sidereal zodiac. This changes ayanamsa by a few arc-seconds compared to JHora 7.5.
(9) When a midpoint was defined as the user defined special point, it was miscalculated in 7.5. It is fixed now.

What's new in version 7.3

1) Jagannatha Hora uses "Swiss Ephemeris" as the planetary calculation engine. The Swiss Ephemeris DLL used by JHora was version 1.64.01 from *June 2002*. It is updated now to version 1.76 from "April 2009*. This brings in several bug-fixes and improvements made in Swiss Ephemeris since June 2002. A notable improvement occurred in version 1.70, where they improved the calculation algorithms to satisfy the latest IAU recommendations. They made the precession model more accurate among other things. For modern dates, this improvement in accuracy makes a difference of a less than a fraction of arc-sec. In fact, for dates after 1000 BC, the difference is less than 1 arc-sec. So it does not matter much. However, for really old dates (e.g. Krishna's chart), this can make a difference of several arc-min in some planets (especially Moon), which can change some divisional charts sometimes. In addition to this improvement in accuracy, several minor bugs, including some in eclipse times, were also fixed.

(2) Weekday and kaala bala of shadbala were miscalculated in old versions of JHora for dates older than 1830 AD. This is fixed now.

(3) In computing SAV, there is an option now to add eight ashtakavargas instead of seven.

(4) Varjya and durmuhurta are added in panchanga. A portion is each nakshatra is marked as varjya (avoidable) and a portion of each weekday is marked as durmuhurta (bad time) and they are avoided traditionally in muhurtas.

(5) Panchanga calculations erroneously showed asterisk on several times sometimes. It is fixed and panchanga page is accurate now.

(6) Vimsottari dasa based on divisional longitudes is fixed.

(7) Ketu's nakshatra transit in mundane tab is fixed now.
(8) Saturn/Ketu exception is restored in antardasas of old style SJC drigdasa. This was erroneously removed when Parasara's drigdasa was added.
There are several other minor bug-fixes and improvements.
