How about the death of Herod?
The belief that Herod died in 4 BC was primarily based on miscalculations, albeit honest mistakes, by Favius Josephus, a Jewish historian (37 – 100 AD), and using the wrong eclipse on March 13, 4 BC. This was just a partial eclipse and very close to Passover that year. Since it's known that Herod died after the eclipse and before Passover, there won't be enough time for the funeral events if this occurred in 4 BC. (Ref: The History of the Jewish People in the Age of Jesus Christ)
On the other hand, there was a full eclipse on January 10, 1 BC. Herod died 18 days after the eclipse, or on January 28, 1 BC. There was plenty of time for his funeral and elaborate memorial services before Passover that year.
Another cause for the misconception of 4 BC death of Herod was the coins minted by Herod's successors which showed their rules beginning in 4 BC. The practice of antedating on the coins is well attested. So the coin is not really a valid proof of Herod's death. (The Birth of Christ Recalculated by Dr. Ernest L. Martin, 1978)
Biblical Timeline
This timeline of 3 BC birth of Jesus and 1 BC death of Herod is further proven by the biblical account in Matthew 2:1-16:
1 Now after Jesus was born in Bethlehem of Judea in the days of Herod the king, behold, wise men from the East came to Jerusalem,
2 saying, “Where is He who has been born King of the Jews? For we have seen His star in the East and have come to worship Him.”
3 When Herod the king heard this, he was troubled, and all Jerusalem with him.
4 And when he had gathered all the chief priests and scribes of the people together, he inquired of them where the Christ was to be born.
5 So they said to him, “In Bethlehem of Judea, for thus it is written by the prophet:
6 ‘But you, Bethlehem, in the land of Judah, Are not the least among the rulers of Judah; For out of you shall come a Ruler Who will shepherd My people Israel.’ ”
7 Then Herod, when he had secretly called the wise men, determined from them what time the star appeared.
8 And he sent them to Bethlehem and said, “Go and search carefully for the young Child, and when you have found Him, bring back word to me, that I may come and worship Him also.”
9 When they heard the king, they departed; and behold, the star which they had seen in the East went before them, till it came and stood over where the young Child was.
10 When they saw the star, they rejoiced with exceedingly great joy.
11 And when they had come into the house, they saw the young Child with Mary His mother, and fell down and worshiped Him. And when they had opened their treasures, they presented gifts to Him: gold, frankincense, and myrrh.
12 Then, being divinely warned in a dream that they should not return to Herod, they departed for their own country another way.
13 Now when they had departed, behold, an angel of the Lord appeared to Joseph in a dream, saying, “Arise, take the young Child and His mother, flee to Egypt, and stay there until I bring you word; for Herod will seek the young Child to destroy Him.”
14 When he arose, he took the young Child and His mother by night and departed for Egypt,
15 and was there until the death of Herod, that it might be fulfilled which was spoken by the Lord through the prophet, saying, “Out of Egypt I called My Son.”
16 Then Herod, when he saw that he was deceived by the wise men, was exceedingly angry; and he sent forth and put to death all the male children who were in Bethlehem and in all its districts, from two years old and under, according to the time which he had determined from the wise men.
Note in verse 11 that Jesus was already a young child when the wise men paid Him a visit. He was at least a year old. Remember, the wise men came from the east. Based on the research of Steven Collins, that was the place where the lost ten tribes of Israel settled down at that time. So the magi were actually noble kinsmen of Jesus. (The "Lost" Ten Tribes of Israel ... Found!)
Royalty caravan, with hundreds of entourage and bodyguards, entailed a lot of preparations and a very long and arduous journey. So it could have taken them at least a year to arrive in Judea from the time the magi saw the symbolic star.
Now, as it says in verse 16, Herod figured out the probable age of Jesus at that time based on when the wise men first saw the star signifying His birth, and had all children two years old and under killed. This is consistent with the 3 BC birth of Jesus and 1 BC death of Herod.
