To download any of the following zip files, click the right mouse on the "Download" link and select "Save target as" in the pop-up menu. The corresponding zip file will be saved on your computer in the directory you choose. Go to that directory in a windows explorer. Locate the zip file and unzip it. You will get a file with the same name, with .zip in the file name replaced by .exe. Run the executable by double-clicking on it. The corresponding installation should start in a few seconds. Read the instructions and follow them. The first screen may give a security warning about an unknown publisher. If you give permission to the installer executable to run by clicking "Run", the installation will proceed.
Read the following carefully and choose the version to download.
1. jh_update.zip (2.6 MB): If you already have Jagannatha Hora version 7.3 (or higher) operational on your computer, you only need this update to move to the latest. Download
2. jh_short_install.zip (3.7 MB): Fresh and short installation of Jagannatha Hora. It contains accurate ephemeris for 1800-2400 AD and uses an approximate analytical model for other dates in 2999 BC-3000 AD. It has a very very small atlas with some important cities. Download
3. jh_full_install.zip (102.0 MB): Fresh and full installation of Jagannatha Hora. It contains accurate ephemeris for 12899 BC-16900 AD. It has a larger atlas with 2.5 million cities. Download
Note: The full version of 8.0 has many more ephemeris files than the full version of 7.66. The "update" does not automatically install all those files. If you want the full range (12899 BC-16900 AD), you should download the full version and install it.
Note: The zip files do not have any problem with them. Many people have successfully downloaded and installed the software. If you are unable to unzip them after downloading them or unable to install, it means that your download did not succeed for some reason. Keep trying until you succeed. We cannot help you with this and there is no use in sending us an email.
We do not distribute or sell the software in CDs. You have to download the software from the internet. You may also try to find someone who has already downloaded it and get them to make a CD for you.
Thank you for using this software. Please use it to help people and to conduct researches to enrich our collective understanding of Vedic astrology. It is the author's earnest and sincere hope that your use of this software will result in a lot of souls being helped and also in a renaissance in the knowledge of Vedic astrology!
