Preserve existing countdown and calendar entity IDs while computing floating holidays from weekday, Gregorian Easter, and Hebrew-calendar rules. Remove obsolete example credentials and expiring date tables, correct Memorial Day and Mardi Gras, and cover the Hanukkah lighting window. Align holiday speech with today/tomorrow countdown values and extend the existing validation gate with calendar, rollover, lighting, and speech checks.codex/local-holiday-calendars

local timezone supplies today's date; --date supports operator previews.
