Krias Hatorah is an integral part of davening. It is arranged so that we complete reading the entire Torah once a year. There are sources for customs that complete the Torah over several years; however, the prevalent minhag today is to finish the Torah every year on Simchas Torah and then begin again on the Shabbos after Sukkos. Our Chachamim split the Torah into 54 Parshiyos to fit into this schedule.

 Some of the questions discussed:

•  When was the takana of Krias Hatorah instituted, and by whom?
•  What was the purpose of this takana - was it to get to know the Mitzvos and understand them better, or to make sure that one learns Torah consistently, as he is required?
•  Does one have to hear the entire Parsha? What if one missed one passuk? What about one letter?
•  Are there halachic differences between the weekday kriah and the Shabbos kriah?
•  What if one missed Krias Hatorah on Shabbos - can he make it up the following week, or by that day's Mincha?
•  What if one missed Krias Hatorah during the week - can he lein by that day's Mincha?
•  When one reads the Torah to make up for a missed kriah, does he need 10 people who haven't heard the leining to join? 

This year, the second day of Shavuos (in Chutz La'aretz) falls on Shabbos (June 12). In Eretz Yisroel, that day is not Yomtov, and they will read the regular Shabbos kriah (Parshas Naso), while those in Chutz La'aretz will read the kriah of Yomtov and will read Parshas Naso the following week. This puts Chutz La'aretz one parsha behind Eretz Yisroel. This affects those who travel between Eretz Yisroel and Chutz La'aretz over this time period. What are the implications, and what is the common practice to resolve this issue?
