After numerous requests, the Zmanim Calendar Generator can now output a less extensive list of zmanim. While the “full” calendar option (the default) generates an Excel spreadsheet with 108 columns of zmanim, the “standard” output generates a spreadsheet with 15 columns containing the most commonly used zmanim. The exact list of what constitutes commonly used zmanim is likely to be tweaked over time. The spreadsheet was initially designed for developers as a sample of the various zmanim available in the API . Developers can compare the output of their zmanim using the API, or a ported version of the API to the spreadsheet for accuracy. Based on feedback, many people use it to generate shul calendars, and wanted a less daunting list of zmanim.
