per https://github.com/KosherJava/zmanim/blob/master/src/net/sourceforge/zmanim/hebrewcalendar/JewishCalendar.java

The methods used to obtain the parsha were derived from the source code of HebCal by Danny Sadinoff and JCal for the Mac by Frank Yellin. Both based
their code on routines by Nachum Dershowitz and Edward M. Reingold. The class allows setting whether the parsha and
holiday scheme follows the Israel scheme or outside Israel scheme. The default is the outside Israel scheme.

I understand that KosherJava started out as GPL, but is now LGPL. Can you describe how that jibes with the GPL nature of the code used here?

@dsadinoff
I thank you for bringing this to my attention. I had years ago requested permission from Avrom Finkelstien when I moved this from a GPL to LGPL not realizing that the code he used was under the GPL. I would like your permission to continue releasing this under the LGPL. If that is not possible I will separate this portion of the code out of the main library, and allow a separate GPL package for the parsha functionality.
Thanks

Due to the history of the hebcal codebase, re-licensing is not an option without permissions from Dershowitz, Reingold, Stallman and perhaps the GNU Foundation, so I wouldn't count on it, sorry.

@dsadinoff
Understood. It will take some time (probably a week) until I get to to separating it.
I would like to take the time to thank you for your pioneer work in open sourcing work so useful for Jews around the world. I don't think the landscape of open source Jewish software would be where it is today if not for your work.

My pleasure. Cheers!

@dsadinoff,
It took much longer than anticipated to get this done. You can see the results in commit 750f7d6.
Thank you for your patience.

[dsadinoff]

Roger that. Thanks.
