Three days and Passover dates confusion... let's clear this up

TWO Questions come up in calendar confusion related to Passover. Let's get these sorted and remember what the holiday is all about. And what Christians can learn from this Jewish holiday. But first, what day was it?

Passover is the holiday that celebrates 'once we were slaves, now we are free.' Deliverance after hundreds of years of slavery in Egypt. God rescued the Jewish people and set a date, 14 Nisan, for us to remember the anniversary under a full moon each year.

Christians also have a day in this season related to Holy Week, the time of the death and resurrection of the Saviour Yeshua/ Jesus. 

There is some overlap and then of course, some real questions. Here are two of them asked, and hopefully answered for you.

QUESTION 1:        3 Days and 3 Nights in the grave

People often ask, “If Jesus said he would be in the ground three days and three nights… how does this work if Good Friday was when he was killed and buried to Easter Sunday when he arose?” That’s more like 36 hours.

Here’s the key:
The Bible uses Jewish time reckoning, not modern Western precision. This is not a Swiss watch.
In Jewish thinking, “Passover” can mean more than one thing.

1. The meal itself (the Seder, 15th of Nisan evening) 

1. The lamb sacrifice (14th of Nisan daytime) 

1. The entire festival week (Passover + Unleavened Bread)

the Passover lambs were being sacrificed. Different calendars; one fulfillment.

In Jewish thinking, any part of a day counts as a whole day. So look at the timeline: Jesus is buried on Friday before sunset — that’s Day 1 which includes Thursday night. He is in the tomb on Saturday, the Sabbath — that’s Day 2 which includes Friday night. And He rises early on Sunday — that’s Day 3 which includes Saturday night.
So Friday, Saturday, Sunday… three days.

Now what about “three days and three nights”? Two answers. 1) As I showed you just now, Friday daytime IS part of the same day as Thursday night. And similarly, Saturday day is Friday night. And Sunday day is Saturday night. Three days: Friday, Saturday, Sunday. Three nights, Thursday to Saturday.

But I prefer unpacking this in a 2^nd way. Why? Since this phrase is a Hebraic expression—a common Jewish way of saying a period spanning three days, not necessarily 72 hours. In fact, no matter what day you start with (and some start with Wednesday, you will never get 72 hours on the dot. He died in the afternoon, and he arose early in the morning. 

But the Hebraic expression is not about 72 hours. It’s a common Jewish way of saying a period spanning three days. Esther fasts and leads the people to fast for “three days, night and day” → yet goes in on the third day (not after 72 hours) (Chapter 4, verse 16)

The Bible itself says repeatedly…He would rise “on the third day.” so there’s no contradiction. It’s not about counting hours—it’s about understanding how Jewish people counted time. And when you do…Friday to Sunday fits perfectly. Sometimes the answer isn’t changing the Bible— it’s understanding the culture in which it was written.
 
Question 2… Was the Last Supper a Passover meal? 

People often notice something in the Gospels that seems to be a contradiction, but it isn’t. Let me explain. Matthew, Mark, and Luke say the Last Supper took place on Passover. And many believers see similarities between the Jewish Passover seder and the Last Supper.

But the apostle John seems to say Jesus died before Passover. So which is it? Who is right? Or can both of them be accurate?

Here’s the key:
The Synoptic Gospels are focusing on the meal, that is, Jesus eating Passover with His disciples. But John is focusing on the timing of the sacrifice. In fact, in John’s Gospel, Jesus is crucified at the very time the Passover lambs are being slaughtered in the Temple.

That’s not a contradiction—that’s theology. Jesus didn’t just celebrate Passover. He became the Passover Lamb. It’s very possible that Jesus followed a Galilean reckoning of Passover, celebrating it with His disciples—while the Temple in Jerusalem followed a different schedule, so that when Jesus died, the official Passover lambs were being sacrificed.

Jesus kept the meal… and became the Lamb.

How do we explain the different timings of Passover in the Gospels? 

Here’s a possibility many people don’t know:
In the first century, not everyone kept the calendar exactly the same way. Jesus and His disciples were from up north in Galilee, while the Temple authorities were in Jerusalem. Some scholars believe Galileans may have reckoned the day differently, thus allowing them to celebrate Passover a little earlier.

That means Jesus could eat a true Passover meal, the seder, with his disciples, and then, the next day which was the same Hebrew calendar date, as the official lambs were being sacrificed in the Temple, Jesus is on the cross. So again, not a contradiction, but a convergence. He keeps the Passover meal, and then he becomes the Passover Lamb. Different calendars, one perfect fulfilment.

Wait; were there actually different calendars in Jesus’ day?
The answer is yes. In the first century, not all Jewish groups followed the same calendar. For example, the community at Qumran—the Dead Sea Scrolls group—used a solar calendar, not the lunar one used in Jerusalem.

That meant their festivals—like Passover—could fall on completely different days. Other groups, including those connected to the Temple, followed the official lunar calendar. So when we read the Gospels, we’re stepping into a world where more than one way of counting time existed.

That helps explain how Jesus could share a Passover meal, and still be crucified at the very time
Because no matter the calendar—Yeshua is the Lamb. History may have had multiple calendars…but God had one perfect timing.
