Passover isn't the actual name of the holiday. The actual name for this holiday is 'Pesach'. The Hebrew word Pesach is a contraction of the words 'peh sach' which means 'the mouth speaks'. The reason for this name is because we are commanded to retell the story of Pesach every year so that we don't forget it.
Passover is an English word that's used because most non-Hebrew speakers can't say the word 'Pesach' properly. Passover refers to HaShem passing over the homes that had lamb's blood painted on their doors in the final plague.
The dates of Passover (or Pesach, as we Jews call it) doesn't need to be calculated like the dates of Easter because it always begins on the same day on the Hebrew calendar - 14 Nisan.
Jews still celebrate Passover to this day.
There is the fast of the firstborn where firstborn males are supposed to fast the day of the eve of Passover. Once Passover starts, there is no fasting.
They welcome the Sabbath and celebrate Passover.
The two days of Passover when no work is allowed are the first day (Passover Day) and the seventh day (the last day of Passover). On these days, Jews are prohibited from engaging in any form of labor or work, as it is considered a day of rest and dedication to religious observances.
The Mashiach (messiah).
In the synoptic gospels, the Last Supper marked the day of the Passover, a day that Jews mark by a ritual meal. The next day, he was tried, crucified and buried. In the Gospel According to John, Jesus washed the feet of the disciples on the day before the Passover, with no particular emphasis on the supper they had. Jesus was tried, crucified and buried on the day of the Passover.
Passover always starts on the 15th of Nisan on the Hebrew calendar. It's the same date every year on the Hebrew calendar.
We pray every day of the year. During Passover, as on all other Jewish festivals, there are additional prayers besides the regular prayers.
