:(Similarly, in activities of anticipatory preparations of decorating and shopping days beforehand, Christians generally regard the entire 24th day of December in the secular western [[Gregorian Calendar]] as the virtual arrival of [[Christmas]] on Christmas Eve even before sunset, and begin to celebrate the arrival of Christmas Day in their churches even before midnight. And the greater majority of Christian believers throughout the major denominations of [[Christianity]] generally do the same with [[vigil]] celebrations of [[Resurrection Sunday|Easter Sunday]], with [[baptism]]s and the [[Eucharist]], often beginning as early as Saturday midafternoon.)
:There are many who do not understand how the day '''preceding''' the fourteenth day of the month could possibly be regarded by any reasonable person as the arrival of "''the first day of Unleavened Bread when the Passover lamb was sacrificed''"—when they "''can plainly see for themselves''" that the Bible explicitly commands the Jews to sacrifice the Passover lamb on the '''fourteenth''' day of the month at evening ("''obviously at the end of the day'''!''''' ") "between the two twilights", '''''not''''' on the preceding evening of the '''thirteenth''' day of the month, which they implicitly assume ends at midnight 00:00 hrs ("''of course '''!''''' "). They mistakenly assert with unquestioning confidence and without any foundation whatever the [[falsehood]] that<br>–the evening and nightfall of the Jewish day is at the end of the day, not at the beginning, <br>–that the Passover lambs were sacrificed in the temple on the fourteenth day of the month during the day as the preparation of the Passover, beginning at noon or midafternoon midway between the two evenings at the beginning and end of the fourteenth, <br>–that the annual Passover ''seder'' was then celebrated at the close of the fourteenth day of Abib/Nisan, at the end of the day beginning at sunset the late afternoon/evening of the fourteenth day of Nisan, as at the '''end''' of the fourteenth day of the month at sunset "between the two evenings" of that day, with the second evening of the day, as being the end of the fourteenth day of Abib/Nisan (14), and the approach of the beginning of the fifteenth day at night<br>–and that the nightfall after sunset at dusk that day "''when three medium stars appear''" is the beginning of the next day, the fifteenth day of Abib/Nisan (15), or that midnight after the fourteenth is the beginning of the next day, the fifteenth <br>–and they reason that the fifteenth day of Nisan as "''the next day''" in the morning through midday and all afternoon '''is''' therefore the day of Passover every year. This is not correct.
::The fourteenth day of the month Abib/Nisan by Jewish reckoning begins very late in the afternoon "at evening" with the approach of sunset and the preparations for the eating of the Passover lamb and continues through sunset and late evening dusk and nightfall with the celebration of the Passover ''seder'' when the Passover lamb is eaten with bitter herbs and unleavened bread and all through the night-long vigil through dawn and morning and all day long through the midday eating of the Passover sacrifice from the flock or the herd (''chagigah'') and early afternoon and midafternoon of the fourteenth day of the month up to very late afternoon/early evening ending the fourteenth day of Abib/Nisan and finally the approach of sunset very late in the afternoon with the beginning of the next day, the fifteenth day of the month "at evening". <br>The first day of Passover is the fourteenth day of the month beginning "at evening" with the Passover seder and extending 24 hours from sunset to sunset, and the beginning of the fifteenth day of the month "at evening".
