The Diocese of Long Island is pleased to release the 2025–2026 Important Dates Calendar. This annual resource is designed to help clergy, lay leaders, and congregations stay informed and plan ahead for the many opportunities that bring our diocesan community together.
The calendar includes a full schedule of diocesan-wide events such as clergy gatherings, youth and young adult programs, celebrations at the Cathedral, grant deadlines, and much more. Whether you are looking to attend formation events, join in worship and fellowship, or keep track of important administrative dates, this guide provides everything in one place.
We invite you to explore the year ahead and mark your calendars with the moments that shape and strengthen our life together.
