The Sunday before Easter, marking Jesus's triumphal entry into Jerusalem.
Palm Sunday begins Holy Week. It commemorates Jesus's entry into Jerusalem, where crowds laid palm fronds on his path. Many Christian traditions distribute palm leaves at services, often woven into crosses, to be kept through the year and burned the following Ash Wednesday.
