Yitzchok ported the Zmanim API from Java to a .NET API using C#. The Zmanim .NET project was released under the LGPL. This is a change from the GPL used by the Java API, something that may change shortly. Also part of the project was the creation of a C# version of the Zmanim CLI, [...]

There are various software projects using the KosherJava Zmanim API. One of the active ones is Jay Gindin’s open source Android Zmanim app for the Android platform. Activity in the project is constant. The upcoming version allows the selection of a specific calculation for zmanim you want such as the zman Talis/Tefilin pictured here. There [...]

An earlier “Bearing to Yerushalayim and Zmanim Map” post demonstrated the use of JavaScript to render the bearing to Har Habayis on a Google Map. A more detailed follow-up post “Technical Information about the Bearing to Yerushalayim Map” dealt with detailed technical information on these calculations. The main Bearing to Yerushalayim and Zmanim Map page [...]

Moshe Wagner who wrote the Zmanim GUI notified me in August that that he created a command line interface for zmanim using my Zmanim API. The technical approach of using reflection was similar to the way I used reflection in the Zmanim Clock Applet, but he took it to new heights. Sample use of accessing [...]

Question: Where is the main method? Answer: This is a more technical variant of the “How do I install the Zmanim API Program?”, but coming from someone who already knows that it is a Java program that can’t be installed, but assumes that it can be run. The main method is the entry point to [...]

The Zmanim API 1.1 was released early this morning. Information about what changed in this release can be seen in previous posts about various beta and patch releases. A last minute change involved the removal of the misheyakir calculations commonly used by the Syrian community. The removal was due to the various different minhagim used, [...]

As hinted at in my previous post , there is a new project underway that uses the Zmanim API in a way that I had never really imagined. Using the Smack API, Michael Kopinsky created the ZmanimBot that allows getting zmanim by instant messaging the ZmanimBot, an internet bot. It currently supports the Google Talk [...]

In December when developing the Zmanim/Bearing to Yerushalayim map (blog post), I noticed a problem with the code used to generate zmanim. The API returns a Java Date object. Usually only the time is of interest, and the date is ignored, but in some cases (when a timezone offset is specified without using the Olson [...]

A while ago, Dr. Irv Bromberg mentioned to me, that my Zmanim API was in use in the Astronomical Clock Applet created by Ali Adams. The applet was a modification to Antony Pranata’s clock applet that displayed Islamic prayer times. Apparently the Zmanim API was so flexible that without any modification it was able to [...]

The Zmanim Calendar Generator is temporarily out of commission due to technical issues being experienced by my web hosting company. My web hosting company was bought out and the new company experienced technical issues in the migration, including Java issues that affect the calendar generation. They have no ETA for a fix.
