Christmas in San Lucas comes in the middle of the coffee harvest season. Most people are picking coffee, and Christmas activities are limited to the evenings and Christmas Day

During the lead up to Christmas day, the 'posada' processions go to a different house each night. Statues of Joseph and Mary are carried in each procession, which is accompanied by children carrying lanterns, blowing whistles and singing carols

On arriving at their destination, the door is closed, and a traditional carol is sung, asking for "posada" - a room for the night. Eventually, the doors are opened, and the procession passes in. Participants are served in the house with hot chocolate or fruit punch, and a tomale or chuchito (corn patties with sauce and meat in their center)

Next evening, the posada leaved that house and goes to the next. On Christmas Eve, all the posadas arrive at the church in time for the evening service. Various "Baby Jesus" are put in the crib in the church before the Mass
