Please be sure to listen to PART 2 

Tomorrow is the fourth Sabbath in the cycle of special Sabbatot that come in the spring time before Purim and Passover.  

It is also a triple header. The rare case of when we open the Hechal and we take out, not, one and not two, but three Sifrei Torah to read from as we do on Simcha Torah.  

In addition to Simcha Torah, a triple header comes when Shabbat falls on Rosh Hodesh Tevet during Chanukah, Rosh Hodesh Adar and as tomorrow Rosh Hodesh Nissan.
