naive OP 30471 booklet (the 2009 reissue of the Alia Vox set), Jordi Savall on the original release: "This recording is based on a selection of the most successful moments from the last two performances recorded live at the Teatro de la Zarzuela in Madrid, on 26 and 28 October 2001." Two nights, so day stays unset; month is October 2001. The years on the folder (2009, 2002) are the naive reissue and the Alia Vox first release, neither of them the sessions.
