Mishkan Torah follows a triennial reading cycle in which one-third of the traditional weekly portion is read each Shabbat. The breakdown that follows was devised by Rabbi Ivan Caine some twenty or thirty years ago (and appears towards the back of the Kol Ha Neshamah siddur).
Readings for Combined Portions: When there is a double parasha, we read the first four aliyot from the first parasha. The final three aliyot and the maftir are read from the second.
The accompanying Haftarah reading can also be found in the pages listed above.
We are currently in the first year of the triennial cycle.
The portion to be read on any given day can be found in this calendar.
