Barnard’s institutional space history dates the Diana Center’s opening to January 2010; contemporary February 2010 announcements describe its public ceremony and visitor tour.
Scope: Morningside Heights, Manhattan · 2010-01-01 – 2010-02-08
Assessment: SUPPORTEDThe directory explicitly supplies January opening, while the architect and Columbia announcements establish the February public phase. They do not justify collapsing academic use, public access and ceremony into one exact first-use day.
Review status: SOURCE_CHECKED_AI_REVIEW. This is not an independently certified universal verdict.
What is not established: The neighborhood report’s original publication date is unresolved; the tour announcement’s last-Monday wording is inconsistent with the Wednesday ceremony description. No exact first-use day or actual ceremony clock time is asserted.
