Speaker: Yehuda Hershkowitz (Jerusalem)

Subject: "Practical and Theoretical Halacha with regard to Calendar
          Making"

Abstract: 
---------
Will discuss the appearence, in the last 20 years, of calendars accurate
to the fraction of a second. Will show how their basic premise is
fallacious and misleading. Will also discuss in passing the various
applications of modern technology to halacha, and will discuss their
applicability or lack thereof.
