zemanim -- a simple calculator for halachic times
ronware is proud to release an Android version of my zemanim application. This version is available on Google Play, and is free.
The Android version displays a "clock" showing the current time as it relates to the various halachic times. The calculations are based upon standard sunrise and sunset algorithms, and are accurate to within two minutes (as mentioned in the application's help, this should be taken into account -- especially regarding shabbat start and end).
If you are interested in having ronware produce Android applications for you, please turn to our website.
Privacy statement
The Android application needs "internet" access, but that is only used when the user wishes to report an issue. In that case, a form is presented on the device, and when the user presses "OK", the issue information is sent to a bug database. However, no private information is sent -- only whatever the user entered, and the version information, display resolution and device model. ronware does not collect private information without specific permission of the user.
The old version
"zemanim" is a command-line program which calculates and displays "halachic times". It is designed to be easily customized by means of the included "ini" file.
Invoking "zemanim" produces a display like:
Halachic times for Maale Adummim:
dawn sunup shema tfila m:ged m:qet m:plg sundn night midnt shaah sedra
10 Oct 2009 05:02 05:38 08:31 09:29 11:53 14:46 15:59 17:12 17:42 23:25 00:57 holiday
16 Oct 2009 05:06 05:42 08:32 09:29 11:51 14:42 15:53 17:05 17:35 23:24 00:56 Bereshit
23 Oct 2009 05:11 05:47 08:34 09:30 11:49 14:37 15:47 16:58 17:27 23:23 00:55 Noach
30 Oct 2009 05:16 05:53 08:37 09:32 11:49 14:33 15:42 16:51 17:21 23:22 00:54 Lech-Lecha
Of course, one may modify the behavior by giving command-line options. For example, invoking "zemanim Chicago 1" gives:
Halachic times for Chicago:
dawn sunup shema tfila m:ged m:qet m:plg sundn night midnt shaah sedra
07 Oct 2009 06:21 06:54 09:46 10:43 13:06 15:58 17:10 18:22 18:55 00:08 00:56 holiday
The various options can be found by invoking "zemanim -h". It is also informative to look inside the "zemanim.ini" file which is distributed with the program.
The current version is 2.02, and is available here. The zip includes Windows, Linux and Mac OS/X versions of the program (which are functionally identical). Unpack the zip file somewhere on your PATH, and enjoy. The 'zemanim.ini' file must be located in the same place as the program file in order for it to take effect.
Halachic Times
Judaism determines correct times for various ritual observances on astronomically visible phenomena. The most important of these are "sunrise", "sunset" and "visibility of three stars".
About
The program is written in Reva Forth, and the source code is available in the examples/zemanim.f file.
Please send Ron your feedback on this program.
