The Passover dinner that is eaten the first night of Passover in Israel, and the first two nights outside of Israel is called the Seder
night of passover
The Seder.
The Jews eat the Passover Seder meal on the night of Passover (Pesach). It makes little difference whether Passover begins on Shabbat or on a weekday. Note that there are festive meals on every Shabbat, but they are not called "seder" and the foods are different.
In Israel, the Seder is on the first night of Passover. Outside Israel, Orthodox and some Conservative Jews celebrate Seders on the first two nights of Passover. Most other Jews have a Seder on only the first night, though some may also have Seders on the first two nights of Passover.
The religious ceremony held on the first two nights of Passover outside of Israel (1st night only in Israel) is called a Seder. The word Seder means 'order'.
The Passover (Pesach) Seder is a special festive meal held on the night of Passover. In it, Jews tell of the Exodus (From a book called the Haggadah) and have specified foods (including matzoh and bitter herb).
Passover is called "Pessa'h" in French. This is not a French word, but comes from Hebrew.
The period after Passover is Sfiras HaOmer. It lasts for 49 days. Be aware that it actually starts on the 2nd night of passover, not after it. This is a count towards Shavuos.
To express how different this night is.
The following was to be done only on the first Passover - the night of the Exodus from Egypt - not on following years. The Israelites put drops of blood of the Passover sacrifice on the doorposts of their homes and the lintel (the top of the doorway). Exodus ch.12.
