Maundy Thursday
The word "maundy" may have come from the maund (or mand) basket
used by the fishermen in the English counties of Norfolk and Suffolk.
Centuries ago, there was a fair held on this day in Norwich (Norfolk),
at which vendors sold horses, cattle and general merchandise. Some of
the fisher-folk brought their maund baskets filled with items to sell,
including fish. Clothing and hats were sold, as it was customary to buy
a new item of clothing for Easter Sunday. This may well have been the
origin of the Easter bonnet and the notion of wearing new spring attire
for Easter.
Maundy Thursday may also have come from the Latin word mandatum, meaning "commandment," as in the Biblical words of Jesus:
"A new command I give you. Love one another. As I have loved you, so you must love one another." (John 13:34, NIV)
Many Maundy Thursday services begin with these words.

Good Friday
The Friday before Easter is called Good Friday,
and is a somber observance of Christ's crucifixion on the cross.
Christians believe that the death of Jesus Christ on the cross made it
possible for them to know peace with God. They wanted to celebrate
their peace rather than observe Friday as a day of mourning or sadness.
The name may also be derived from God's Day, since in the first two centuries, the word "good" would only ever have been used as a description for God. The Saxons and Danes called this day Long Friday, and Good Friday in Danish is Langfreday.

Easter Sunday

"Do not be alarmed," he said. "You are looking for Jesus the Nazarene, who was crucified. He has risen! He is not here. See the place where they laid him." (Mark 16:6, NIV)
It is important to understand that Easter was not celebrated or mentioned in the Bible. Rather, the three-day period from Good Friday through Easter Sunday has become a traditional observance of when Christians believe that the crucifixion, burial and resurrection of Christ occurred.
