Why is Holy Thursday called Holy Thursday?

We celebrate Holy Thursday because it was The Last Supper, and when Jesus washed the feet of the disciples. This was a special day, the day before Jesus was Commended to death. Before all the 15 Stations of the Cross began. Similar to the Last Supper instead of using a long table for Christians, we eat the body of Jesus (the Eucharist) and drink the blood of Jesus (the wine) every Sunday at mass. Every year we repeat these Holy days to show our faith as Christians.
