About This Site

Zmanim is a series of software packages that computes zmanim, the times (according to Jewish law) by which an observant Jew must complete specific prayers and other religious obligations.
There are currently the following components available.
There is an online application that uses the Zmanim Java API to generate a full year of zmanim in an Excel spreadsheet. For developer information on the Java API, please browse the zmanim JavaDocs.


While we did our best to ensure the quality of our code, we can't gaurantee the accuracy of the calculations. Please consult your local Rabbi if you have any questions about zmanim.
