We fetch this document again every day and compare it with the version we verified; if the district changes it, the dates here are read again.

Note: Oct. 12-16 is a full week with no school (District Collaboration Day, Teacher Professional Development, Parent-Teacher Conference Exchange Date, Fall Break). Inclement Weather Days (Mar 12, Apr 9, Apr 26, May 27 and May 28) are used in consecutive order as regular school days to make up missed time; any unused one is a no-school day. If none are used, the last day of school would be effectively earlier than May 28, since the calendar shows May 28 as the last day. Mar 12 is also the end of 3rd quarter. Parent-teacher conferences are evenings only (elementary Oct 1 & 6, Mar 4 & 9; secondary Sept 24 & 29, Feb 25 & Mar 2), not days off. Memorial Day (May 31) falls after the last day. Calendar says it is subject to change and does not state board approval. District Collaboration Days are listed as No School and placed in days_off using the document's wording.
