[916] My hour has not yet come

4 But Jesus said to her: What have I to do with you, woman? My hour has not yet come. (John 2 NWT)
30 Hence they began seeking to get hold of him, but no one laid a hand upon him, because his hour had not yet come. (John 7 NWT)
20 These sayings he spoke in the treasury as he was teaching in the temple. But no one laid hold of him, because his hour had not yet come. (John 8 NWT)

23 But Jesus answered them, saying: The hour has come for the Son of man to be glorified. (John 12 NWT)

1 Now, because he knew before the festival of the Passover that his hour had come for him to move out of this world to the Father, Jesus, having loved his own that were in the world, loved them to the end. (John 13 NWT)

So the hour ran from Palm Monday on 33Nisan10 (when the sheep enters the house on an asses colt in this case) to the Pentecost on 33Sivan5 when the Alienation Times ended because Jesus completed his sacrifice and became divine. That is 55 days. Whereas his entire ministry ran from 29Tishri10, his baptism by John to 33Sivan5, his glorification as God number 2. 1315 days. 

9 Jesus answered, Are there not twelve hours in the day? If anyone walks in the day [daylight day], he does not stumble because he sees the light of the world. (John 11 GLT)

Yes, there are 12 hours in the daylight day and there are 24 hours in the calendar day. The day light day ends with its evening at darkness, the calendar day ends with its evening at sunset. This is a classic example of the Binary Question Principle. Both answers are true.

Let's have 24 hours in the day of his entire ministry. Then 1315/24 = 54.8. Now the gifts of the spirit were poured out at the 3rd hour of the day of Acts2. So Jesus must have entered into the temple 0.2 of a day or 4.8 hours after then i.e. around the 8th hour of the day on 33Nisan10.

Incidentally this means that although Jesus arrived at Bethany 6 days of John 12:1 before the Passover, he arrived before sunset. So he had the evening meal 5 days before the Passover and Palm Monday (the next day of John 12) was 33Nisan10, 4 days before the Passover - when the Passover victim is supposed to enter into the house according to law:

1 Accordingly Jesus, 6 days before the Passover [33Nisan8 before sunset], arrived at Bethany, where Lazarus was whom Jesus had raised up from the dead.
2 Therefore they spread an evening meal for him there [33Nisan9, after sunset], and Martha was ministering, but Lazarus was one of those reclining at the table with him.
12 The next day [33Nisan10 - Palm Monday] the great crowd that had come to the festival, on hearing that Jesus was coming to Jerusalem,
13 took the branches of palm trees and went out to meet him. And they began to shout: Save, we pray you! Blessed is he that comes in Jehovah's name, even the king of Israel! (John 12 NWT)

So it was not Palm Sunday - It was Palm Monday, when he rode into Jerusalem upon the colt of an ass and entered into the temple as the Passover victim!
