The Diocese of Long Island has released a revised version of the 2025–2026 Important Dates Calendar. This essential resource helps clergy, lay leaders, and congregations stay informed and organized for the many opportunities that bring our diocesan community together.
Please look for “Revised 10/2025” in the lower right-hand corner of your calendar to ensure you have the most current version. We encourage all parishes to download and print the updated calendar for use in their offices.
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’re planning to attend formation events, join in worship and fellowship, or keep track of key administrative dates, this guide provides everything in one place.
We invite you to review the updated calendar and mark the moments that continue to shape and strengthen our shared life together.
