These are the dates I mark in September — drawn from the institutional, cultural and intellectual record. September carries Heritage Month, with Heritage Day on the 24th; it holds the unfinished business of the transition, and it is the month Biko died and Cabral was born. Every entry has been verified against at least two independent sources. Where only the month of an event is documented, no day is invented. No publication commitments are implied.
