Seven Days In Gospel of John

In Genesis, there was "In the beginning" and followed by seven days of creation.
In John, there was "In the beginning" and followed by seven days of John and Jesus.

The following division was given by Dr Tim Berrey:
1st day John 1:19-28
2nd day John 1:29-34
3rd day John 1:35-39
4th day John 1:40-42
5th day John 1:43-51
6th day (not mentioned)
7th day John 2:1-11

First day
This was John's testimony when the Jews from Jerusalem sent priests and Levites to ask him, "Who are you?" He didn't deny it but confessed: "I am not the Messiah." "What then?" they asked him. "Are you Elijah?" "I am not," he said. "Are you the Prophet?" "No," he answered. "Who are you, then?" they asked. "We need to give an answer to those who sent us. What can you tell us about yourself?"
He said, "I am a voice of one crying out in the wilderness: Make straight the way of the Lord - just as Isaiah the prophet said." Now they had been sent from the Pharisees. So they asked him, "Why then do you baptize if you aren't the Messiah, or Elijah, or the Prophet?" "I baptize with water," John answered them. "Someone stands among you, but you don't know him. He is the one coming after me, whose sandal strap I'm not worthy to untie." All this happened in Bethany across the Jordan, where John was baptizing. (John 1:19-1:28 CSB)

Second day
The next day John saw Jesus coming toward him and said, "Here is the Lamb of God, who takes away the sin of the world! This is the one I told you about: ‘After me comes a man who ranks ahead of me, because he existed before me.' I didn't know him, but I came baptizing with water so he might be revealed to Israel." And John testified, "I saw the Spirit descending from heaven like a dove, and he rested on him. I didn't know him, but he who sent me to baptize with water told me, ‘The one you see the Spirit descending and resting on - he is the one who baptizes with the Holy Spirit.' I have seen and testified that this is the Son of God." (John 1:29-34 CSB)

Third day
The next day, John was standing with two of his disciples. When he saw Jesus passing by, he said, "Look, the Lamb of God!" The two disciples heard him say this and followed Jesus. When Jesus turned and noticed them following him, he asked them, "What are you looking for?" They said to him, "Rabbi" (which means "Teacher"), "where are you staying?" "Come and you'll see," he replied. So they went and saw where he was staying, and they stayed with him that day. It was about four in the afternoon. (John 1:35-39 CSB)

Fourth day
Andrew, Simon Peter's brother, was one of the two who heard John and followed him. He first found his own brother Simon and told him, "We have found the Messiah" (which is translated "the Christ"), and he brought Simon to Jesus. When Jesus saw him, he said, "You are Simon, son of John. You will be called Cephas" (which is translated "Peter"). (John 1:40-42 CSB)

Fifth day
The next day Jesus decided to leave for Galilee. He found Philip and told him, "Follow me." Now Philip was from Bethsaida, the hometown of Andrew and Peter. Philip found Nathanael and told him, "We have found the one Moses wrote about in the law (and so did the prophets): Jesus the son of Joseph, from Nazareth." "Can anything good come out of Nazareth?" Nathanael asked him. "Come and see," Philip answered. Then Jesus saw Nathanael coming toward him and said about him, "Here truly is an Israelite in whom there is no deceit." "How do you know me?" Nathanael asked. "Before Philip called you, when you were under the fig tree, I saw you," Jesus answered. "Rabbi," Nathanael replied, "You are the Son of God; you are the King of Israel!" Jesus responded to him, "Do you believe because I told you I saw you under the fig tree? You will see greater things than this." Then he said, "Truly I tell you, you will see heaven opened and the angels of God ascending and descending on the Son of Man." (John 1:43-51 CSB)

Seventh day
On the third day a wedding took place in Cana of Galilee. Jesus's mother was there, and Jesus and his disciples were invited to the wedding as well. When the wine ran out, Jesus's mother told him, "They don't have any wine." "What does that have to do with you and me, woman?" Jesus asked. "My hour has not yet come." "Do whatever he tells you," his mother told the servants. Now six stone water jars had been set there for Jewish purification. Each contained twenty or thirty gallons. "Fill the jars with water," Jesus told them. So they filled them to the brim. Then he said to them, "Now draw some out and take it to the headwaiter." And they did. When the headwaiter tasted the water (after it had become wine), he did not know where it came from - though the servants who had drawn the water knew. He called the groom and told him, "Everyone sets out the fine wine first, then, after people are drunk, the inferior. But you have kept the fine wine until now." Jesus did this, the first of his signs, in Cana of Galilee. He revealed his glory, and his disciples believed in him. (John 2:1-11 CSB)
