The Hebcal Torah Reading pages specify both the traditional full kriyah (reading the entire weekly Torah portion each Shabbat) and also a triennial cycle specified by the Conservative Movement in the United States.
“Many congregations pattern their weekly Torah reading cycle after a system similar to the one used in ancient Israel during the rabbinic period. In this system, the traditional parashiot are each divided into three shorter segments, and the whole Torah is completed once every three years. The system has both advantages and disadvantages, but its ability to shorten the length of Torah reading without sacrificing the complete reading of the Torah on a regular basis has made it the choice of some synagogues in the Conservative Movement.”

Masorti triennial schedule for Israel
Although there is no formally specified triennial cycle for the Masorti movement in Israel, Hebcal began publishing a draft schedule in May 2023. Due to differences in the Torah readings schedule based on keeping only a single day of chag in Israel, the Diaspora triennial system does not work for a small number of parsha combinations that can occur in Israel.
In particular, Behar-Bechukotai and Matot-Masei occasionally occur with different 3-year patterns in Israel that never occur in the Diaspora. Rather than invent new aliyot divisions for Israel, we have adapted/reused the existing triennial variations used in the Diaspora.
Here is the draft schedule with some example years where the 3-year patterns occur.
Behar-Bechukotai
- 3-year pattern SSS (Separate in years 5774, 5775, 5776)
- SST (Separate in 5789, Separate in 5790, Together in 5791)
- TSS (Together in 5777, Separate in 5778, Separate in 5779)
Matot-Masei: 3-year pattern “STS” (Separate in 5774, Together in 5775, Separate in 5776)
