As you know that we have a Janma Kundali and Prashna Kundali Software on http://www.astrosage.com/. With the availability of new tools and technology, we felt a need for a quicker, easier and more flexible method for creating detailed Kundali.
Keeping it in mind, we have desinged a new and powerful interface for the instant chart feature of AstroSage.com and this new interface can be found at http://www.mykundali.com/.
In this new interface, you can type some characters of your city name and it will fetch the cities matching with that name and populates city details there itself. You can then select the city using your mouse. In case you are not satisfied with the latitude/longitude or the city is not there in the database, you can type your own latitude/ longitude/ timezone.
Please try http://www.mykundali.com/ and let us know your feedback. Please note that the software is still in beta and your feedback will help in improving it. Also if you like this software, please tell it to your friends and family members so that they can also utilize it.
