I read in a guidebook that the Christmas festivities start early here. Celebrated on December 7th in Leon and December 8th in the rest of the country, La Griteria Immaculate or the Feast of the Immaculate Conception is a Roman Catholic holiday. We celebrated it growing up with a special Mass and dinner at my grandparent's house. Here in Nicaragua where the majority of the population is Roman Catholic, these feast days become big celebrations.
