Query: Correction to my earlier review

My quick scan of Dec. 16 in the calendar didn't include the actual lengthy text, which *does* refer to Sir Arthur's birthday, as it is a rumination on the anticipated arrival of ACC's 84th birthday. Unlike most calendars that stick to a theme, this calendar still tends to ignore major events in the SF world and does not delineate them -- nor is there a delineated reference to Sir Arthur's birthday. Sorry about the confusion!!!
