It depends upon the denomination you are speaking of. A small group in Christianity celebrate it on the 14th day of the first month (Nisan) after sunset.
Roman Catholics celebrate the Mass of the Last Supper.
The Last Supper
Jesus attended only one supper, hence the name "last supper." At the last supper, Jesus instituted the Eucharist and laid the foundation for the Catholic Mass. Many other Christians today celebrate this "last supper" on Sunday mornings at church as a means of symbolic reunion with God.
The Eucharist taken during mass is prescribed during the Last Supper. (Take this wine as my blood and this wafer as my flesh...)
At the Last Supper
Jesus Christ offered the first mass at the Last Supper.
Mass, which is a memorial of the death and resurrection of Christ, involves the breaking of bread and drinking wine. The first time that this (the breaking of bread and wine) was established was at the 'Last Supper'.
At the Last Supper, the night before Jesus died.

You have that backward, the first Eucharist occurred during the celebration of the Last Supper, and the second half of the Mass, called the Liturgy of the Eucharist (used to be called the Mass of the Faithful) is based on the Last Supper, and the Passover meal which is was. The Eucharist is based on the third cup of wine at the Passover meal.
Christ did at the Last Supper. He also taught about it in John 6.
