Sunday is a Christian moveable feast
that falls on the Sunday before Easter . The
feast commemorates Jesus' triumphal entry
into Jerusalem , an event mentioned in all
four canonical Gospels .

In many Christian churches, Palm Sunday
includes a procession of the assembled
worshipers carrying palms, representing
the palm branches the crowd scattered in
front of Jesus as he rode into Jerusalem.
The difficulty of procuring palms in
unfavorable climates led to their
substitution with branches of native trees,
including box, yew , willow , and olive. The
Sunday was often designated by the names
of these trees, as in Yew Sunday , or by the
general term Branch Sunday .
