A set of scripts (bash and awk) used to produce localized planet rise and set times based upon output from aa (Stephen L. Moshier's astronomical almanac program). Output formats include the raw output from aa, CSV, HTML, tabular, and postscript.
planet-rs.sh takes a standard aa input file (refer to my post on aa for an example) and, optionally, format (raw, csv, html, or ps), time zone and a time zone label. In the example outputs below, rise and set times are displayed for Jupiter in July, 2022, EDT (-4 hours from UT).

Here's an example of the HTML output. The example postscript output was converted to PDF using ps2pdf.
The lod.awk
script takes CSV output and calculates day lengths.
jeffr@Europa: ~/planet-rs $ ./planet-rs.sh Sun-12-2022.txt csv -5 EST | head | awk -f lod.awk Date, Length of Day 12/01/2022, 9:33 12/02/2022, 9:31 12/03/2022, 9:30 12/04/2022, 9:29 12/05/2022, 9:28 12/06/2022, 9:28 12/07/2022, 9:27 12/08/2022, 9:26 12/09/2022, 9:25
The today.sh
script shows sunrise, sunset, and length of day for the current day.
jeffr@Europa: ~/planet-rs $ ./today.sh Date, Sunrise, Sunset 11/14/2024, 07:21 EST, 17:20 EST Date, Length of Day 11/14/2024, 9:59
The package below includes a sample aa.ini (edit to reflect desired latitude, longitude, etc.) as well as input files for various planets. The scripts have been tested on Ubuntu Linux and Cygwin.

If you get an error message similar to the following when attempting to use the ps output format:
troff: fatal error: can't find macro file s
It may be due to a missing Groff macro. I solved this issue on Ubuntu Linux by installing the complete Groff package (in addition to the base package, which is installed be default).
