It is the Sunday before Easter,signifies the beginning of the last week of Lent — and the beginning of Holy Week.
After attending the Holy Mass, people gather outside the church and wait for the parish priest to begin the ceremony.
It starts by reading a verse from the bible, followed by a simple prayer and ends by blessing of the palms with holy water while people keeps waving the palms on their hands.
In essence, the parishioners join this celebration to praise Jesus and ask Him to be their savior and healer. Palm Sunday
