Here is the 2009 official Puerto Vallarta City Calendar of holidays and celebrations. The print is small and in Spanish so click to enlarge to read. Courtesy of the Puerto Vallarta Culture Department. This listing shows all governmental holidays and how the Mexican flag should be flown (full or half staff), where the official ceremony will be held and if civic personnel have to attend. Full staff flying of flags indicates a basic holiday. Half staff indicates a current or historical date of death.
