Zmanim API 1.2 Released


The Zmanim API 1.2 was released today. The only change in this release is the removal of elevation as a factor in the calculation of all zmanim besides sunrise and sunset. Updated JavaDocs now reflect these changes. Please see the Elevation Now Only Impacts Sunrise and Sunset Calculations in the Zmanim API post for additional information.

I would like to thank the various people who contacted me on the subject.

The main download is the Zmanim 1.2 release zip file that includes source files and JavaDoc documentation. Also available for download (included in the above zip file) is the main zmanim-1.2.jar. The zmanimAstronomical-1.1.jar that only includes the AstronomicalCalendar was not impacted by this change, but the version has been updated to zmanimAstronomical-1.2.jar for consistency. Additional detail on the downloads can be seen on the Zmanim Download page

Zmanim API 1.1 Released


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, and Chacham Yosef Harari-Raful not endorsing any one, or including any, in his calendar. The API is flexible enough to be used for any calculation wanted by the various Syrian shuls even without “native” support for a built in “Ateret Torah” misheyakir. Some missing JavaDocs were also added.

I would like to again thank Rabbi Rachamim Ashkenazi the publisher of a zmanim calendar for the Syrian Community, and Victor Grazi for his input, testing and technical expertise used for adding the new “Ateret Torah” zmanim.

The main download is the Zmanim 1.1 release zip file that includes source files and JavaDoc documentation. Also available for download (included in the above zip file) is the main zmanim-1.1.jar and the new zmanimAstronomical-1.1.jar that only includes the AstronomicalCalendar and supporting classes. Additional detail on the downloads can be seen on the Zmanim Download page.

Zmanim GUI Released

Zmanim GUI screenshotI was recently contacted by Moshe Wagner who wanted to know if there was a graphical front end to the Zmanim API. While there are various programs that do use the API, there is no standalone Java GUI that uses the API (the zmanim clock applet is not easily useful for looking up zmanim for various locations). As first announced in Hebrew ( ZmanimGUI – ממשק להצגת זמני היום ההלכתיים ), Moshe took the API and wrote a Java Swing GUI for the API. The Zmanim GUI (called זמני היום in Hebrew) can switch between Hebrew and English display and shows the most common list of zmanim typically used. The program requires Java 6 and can be launched by double clicking on the ZmaniGui jar file (or execute the command ‘java -jar ZmaninGui.jar’ from a command prompt). As with the Zmanim API, the GUI was released under the GPL2 and is available (including source) on our download page (direct link to version 0.0.87 updated on May 12, 2009). Questions and comments can be posted here, or sent directly to Moshe at moshe.wagner -AT- gmail.com.

Zmanim API 1.1 Beta 3 Released


The third beta release of the Zmanim API 1.1 is now available on the download page. The main change in this release is the addition of zmanim based on the psak of Chacham Yosef Harari-Raful of Yeshivat Ateret Torah. These zmanim were requested by members of the Syrian Community. Other changes in this release include various additions and fixes to the API JavaDocs. I hope to post some detailed information about the new “Ateret Torah” zmanim in the near future. I would like to thank Rabbi Rachamim Ashkenazi the publisher of a zmanim calendar for the Syrian Community for his help with the “Ateret Torah” zmanim.

The main download is the Zmanim 1.1 beta 3 release zip file including source files and documentation. Also available for download (included in the above zip file) is the main zmanim-1.1_beta_3.jar and the new zmanimAstronomical-1.1_beta_3.jar that only includes the AstronomicalCalendar and supporting classes.

Zmanim API 1.1 Release Candidate Available


A release candidate (RC1) of the Zmanim API 1.1 is now available on the download page. Changes in this release include a slight clean up of the recently released NOAACalculator code (does not change calculated times), as well as fixes to the date (but not time) of calculations for locations near the arctic circle. This date fix builds on the February release of the API to fix an arctic circle issue and a similar issue encountered when trying to generate zmanim for locations other than the local timezone. Also included in this release is the zmanimAstronomical-1.1.jar, a release that only includes the AstronomicalCalendar class and supporting classes. There was also some code refactoring to make the code easier to maintain. A detailed post will follow (hopefully within the next week or so).
