👂︎ Public Readings, Sources, and Cantillation // Festival & Fast Day Readings // Readings for Civic Days on Civil Calendars // π Day Readings ![]() ![]() There is a Rabbinical tradition that the value of pi is hidden within a ktiv-kri (reading-versus-writing disparity) in I Kings 7:23. According to Hebrew scriptural tradition, the word meaning ‘line’ is written as קוה, but read as קו. . . . 💬 הַפְטָרָה לְחַג הַפַּאי | Haftarah for the Festival of π (I Kings 7:23-26 and 8:54-66), the twenty-second day of the seventh month (which falls on Shmini Atseret)![]() Shmini Atseret is a strange festival. In some ways part of Sukkot, in some ways its own thing, it occupies an equivocal place in the yearly cycle. But one thing that is completely true: Shmini Atseret is on Pi Day. Well, Pi Approximation Day — the twenty-second day of the seventh month. Inspired by my friend and math enthusiast Aryeh Baruch (may he have a long life), I’ve compiled this altered form of the haftarah for Shmini Atseret in the diaspora, including the description of King Solomon’s “molten sea,” as well as an Aramaic “reshut” poem with a numeral acrostic of the first few digits of pi. . . .

The Open Siddur Project is a volunteer-driven, non-profit, non-denominational, non-prescriptive, gratis & libre Open Access archive of contemplative praxes, liturgical readings, and Jewish prayer literature (historic and contemporary, familiar and obscure) composed in every era, region, and language Jews have ever prayed. Our goal is to provide a platform for sharing open-source resources, tools, and content for individuals and communities crafting their own prayerbook (siddur). Through this we hope to empower personal autonomy, preserve customs, and foster creativity in religious culture. If you like what you've found here, please help keep our project alive and online with your financial contribution.
