When is a seder plate used passover or all Jewish holidays?

Anyone who is hosting a Passover Seder (the ritual dinner on the first two nights of Passover), would have a Seder plate. It's usually placed in the center of the dinner table. It is a special plate containing symbolic foods eaten and displayed during the Passover Seder.

The foods are arranged on the plate has special significance to the retelling of the story of the exodus from Egypt, which is the focus of the Seder. There are 6 ritual items, five of them are on the Seder Plate:

• Bitter herbs, symbolizing the bitterness of slavery, which the Hebrews endured in Egypt.

• A sweet mixture of chopped nuts, grated Apples, cinnamon, and sweet wine called "Charoset", represents the mortar used by the Jewish slaves in building Egypt.

• A vegetable, usually Parsley or Endive , which is dipped into salt water to represent the tears of the Hebrew slaves in Egypt.

• A roasted lamb or shankbone, chicken wing, or chicken neck; symbolizing the Passover sacrifice, which was a lamb that was offered in the Temple in Jerusalem. This item is not eaten.

• A hard-boiled egg, symbolizing the mourning of the destruction of the Temple and our inability to offer any kind of sacrifices in honor of the Passover holiday today. (eggs are the first thing served to mourners after a funeral)

• The sixth ritual food is Matzos, which is placed on a separate plate.

There are many decorative and artistic Seder Plates, but any plate large enough to hold all the ritual food items can be used.
