Passover

For the first Passover in Egypt, HaShem instructed the Israelites to slaughter lambs and paint their door posts with the blood. They were to then roast the meat and eat it that night.

The significance of this was that by slaughtering lambs, the Israelites were performing an act that was an outright rejection of the Egyptian Gods. This is because lambs were one of the animals worshiped by the Egyptians. By marking their doorposts with the lambs' blood, they were showing their acceptance of HaShem.

After the Exodus, lambs were slaughtered, roasted, and eaten by families as offerings of thanks to HaShem every Passover. Today, the majority of Ashkenazi Jews do not eat lamb during Passover as the Temple is not standing. Most other Jewish groups do eat lamb though.

Passover, known to Jews as Pesach, is made a mandatory annual event in the Bible (Leviticus 23:5) and as such was established in ancient times. Although it is impossible to put a precise date on the Exodus, from which the holiday originates, it seems evident that it was already an honoured and ancient tradition by the time that the Torah was written down, possibly between 538-334 BCE (BC).

Bible scholars, who have estimated the dates of various events by looking at the lifespans of biblical characters, place the date of the Exodus to around 1447 BCE. However, there is no physical evidence, and since it is generally agreed nowadays that Old Testament figures (such as Methuselah, 969 years) did not live for as long as the texts claim there are various conflicting modern attempts at dating the Hebrews' escape from slavery in Egypt. The so-called Late Exodus theory dates the event to between 1250-1200 BCE, while Early Exodus proponents claim 1440 BCE. Some Early Exodus believers also argue that there were in fact two Exoduses: the first, in 1628 BCE, was in response to a volcanic eruption in Minoa which is thought to have caused most of the biblical Plagues. The second is then said to have taken place in 1450 BCE.

If one of these dates is correct, we can assume that Pesach was established as an annual festival either that same year or very soon thereafter.

You're thinking of Passover or Pesach (פסח), but this holiday was not created from the plagues by Moses.
The Ancient Hebrews created this holiday to commemorate their freedom and the Exodus from Egypt. The Plagues are only a small part of the story.

The exodus from Egypt.

The highlight of Passover is the Seder meal, called the Passover (Pesach) Seder, which is of great importance in Judaism. It is a 3325-year old continuous tradition that began on the night of the Exodus from Egypt (see Exodus chapter 12), and is fully detailed in our ancient Oral Traditions (Talmud, perek Arvei Pesachim).

The Seder meal is one of those occasions, like Yom Kippur and Hanukkah, that Jews all over the world, Orthodox and non-Orthodox alike, have in common. During the Seder, we keep the essential mitzva and customs of handing Jewish traditions down to the next generation, with the traditional Seder foods and the ceremony of reading the Passover Haggadah which retells the events of the Exodus.

It is possible to get tahini that is hechshered kosher l'Pesach. However, these products are kitniyot so the majority of Ashkenazi Jews would not eat it.

This is a matter of individual outlook and opinion; you could probably get 10 different answers from 10 different people. Here's a suggested answer from this responder: From the observance of Pesach (Passover), Jews gain: -- an appreciation of freedom in a very strict sense ... freedom directed to a purpose, not simply to enjoy liberty but to make liberty an instrument of purpose; as Paul Harvey used to say, "not free to do as you want, but free to do as you ought", which is the service to the Master of the Universe, and exemplifying his meaning and message to the nations of the earth; -- an inspiration to look for the Deity not among themselves or among the objects of nature or of legend, but to the Power which permeates, yet transcends, all of creation; this idea is driven home first by the fact that the Pesach commemoration and celebration virtually ignore Moses. -- an awareness that worship consists not only of prayer but equally of study and learning, which are emphasized from the first moment of the holiday; -- an awareness of the central, vital importance of the children to the survival of the Jewish lessons and way of life; -- a sense of humility and gratitude toward the infinite Power that saw fit not only to teach Pharaoh and his people a lesson in return for their treatment of the Jews, but also to rescue the Jews in the process, and to give them the resources and set them on a new life course of their own.

Aaron was Moses' older brother and the first High priest of the nation of Israel.

There is no prohibition against kissing during Passover.

Before the holiday starts, Jews clean their homes from top to bottom to remove any trace of 'chametz' (leavened bread and anything that has forbidden food items). Once that is done, completely new food that meets the additional requirements for Passover are purchased and prepared.

The first night in Israel and first two nights outside of Israel involve a religious service called a 'Seder' which is held in the home around the dining table. At this service, prayers are recited, symbolic foods are eaten in a specific order, and the story of the exodus from Egypt is read. Partway through the service dinner is eaten. After dinner the religious service is completed.

For the whole holiday (7 days in Israel, 8 days outside of Israel), no leavened products are eaten, this includes pasta, and all other products made from the grains that aren't allowed. Instead, matzah and foods made with matzah by-products are eaten.

Yes, there are no restrictions on fruit for Passover.

I assume that you are referring to the Ten Plagues in Exodus. In order, they are:

1) The plague of water turning into blood

2) The plague of frogs

3) The plague of gnats

4) The plague of flies

5) The plague of livestock death

6) The plague of sores

7) The plague of hail

8) The plague of locusts

9) The plague of darkness

10) The plague of first-born death

Passover 2017 begins at sunset on Monday, April 10 and ends in the twilight on Tuesday, April 18. In Israel, the holiday begins on the same day as outside Israel, but ends one day earlier.

More about Passover

Jews still celebrate Passover to this day.

Jews take droplets out of their wine glasses during the Passover Seder in order to acknowledge the pain and suffering that the Egyptians underwent for the Israelites (the Jews' Ancestors) to attain their freedom. It is critical to acknowledge the humanity of all people, not just those of your own tribe or group and Judaism uses the removal of wine as a symbol of this fact.

it's a story from the bible - when God sent various plagues to Egypt to force the then king to release the Jewish people from slavery. God said he was going to kill the first born son of every household - but told the Jewish people to mark their doors with blood so the Holy Spirit would 'pass over' their homes, allowing their children to live.

During the passover festival, the Jews remember their exodus from Egypt.

The exodus of the Jews from Egypt The story is: Moses kept speaking to the Pharoah begging him to let the Israelite slaves free. The Pharoah said no so Moses said that God would send down 10 plagues to Egypt. These were: blood, frogs, lice, wild animals, sick animals, boils, hail, lcousts, darkness and, worst of all, the death of the first born. The Israleites would avoid the 10th plague by painting a red cross on their door of lamb's blood. If they did this, the plague would 'pass over' them. This is where passover got its name. Eventually, the Pharoh surrendered and told Moses to lead the slaves out of Israel.

Passover always starts on the 15th of Nisan on the Hebrew calendar. It's the same date every year on the Hebrew calendar.
