The Of Many Institute for Multifaith Leadership is a pioneering initiative devoted to educating and inspiring religious and spiritual leaders to utilize multifaith dialogue and service as a force for positive social change. Started in 2012 by Chelsea Clinton, Khalid Latif, Linda Mills, and Yehuda Sarna, The Of Many Institute is home to all multifaith resources and programs on campus.
In addition to regular programming and events, Of Many offers nationally-recognized educational tools such as Faith Zone trainings, Deep Dialogue trainings to foster conversation on complex socio-religious issues, and the first academic minor of it's kind sponsored by NYU Silver and NYU Wagner. The Of Many Institute also houses the Multifaith Advisory Council, a diverse, interfaith student organization dedicated to multifaith work at NYU.
The Diversity Awareness Partnership has compiled a calendar of observances and holidays celebrated across 25 traditions (PDF) that is a useful resource for clubs as they choose meeting dates, for University offices as they plan marquee events, and for community members to honor the holidays of friends and colleagues. You can also check out this Interfaith Calendar or search Google Calendars for specific faith traditions that you can use alongside your own Google calendar.
NYU Residential Life and Housing Services offers a monthly online educational series using Twitter (@NYUHousing). Follow #NYUObserves and #NYUCelebrates to learn more about upcoming religious observances and celebrations from a wide range of faith traditions.
