How did Jesus know that the week before Palm Sunday were his last days?

Jesus understood that the week before Palm Sunday was significant due to his prophetic awareness and teachings about his impending death and resurrection. He had previously foretold his passion to his disciples, indicating that he would suffer, be killed, and rise again. Additionally, his actions during that week, including his entry into Jerusalem and cleansing of the temple, reflected a deliberate fulfillment of prophecy and acknowledgment of the urgency of his mission. This heightened awareness of the events leading to his crucifixion underscored the culmination of his earthly ministry.
