'Year' in the Bible

In the third year of the reign of King Jehoiakim of Judah, King Nebuchadnezzar of Babylon came to Jerusalem and laid siege to it.

So Daniel remained there in service until the first year of King Cyrus.

During the second year of Nebuchadnezzar's reign, Nebuchadnezzar had dreams that troubled him. As a result, he couldn't sleep.

About a year later, as the king was walking on the roof of the royal palace of Babylon,

In the first year of the reign of King Belshazzar of Babylon, Daniel dreamed a dream, receiving visions in his mind while in bed, after which he recorded the dream, relating this summary of events.

"During the third year of King Belshazzar's reign, I, Daniel, saw a vision after the earlier vision that had appeared to me.

"In the first year of the reign of Darius son of Ahasuerus, a descendant of the Medes, who was made king over the kingdom of the Chaldeans

in the first year of his reign I, Daniel, noted in the Scripture the total years that were assigned by the message from the LORD to Jeremiah the prophet for the completion of the desolations of Jerusalem: 70 years.

In the third year of Cyrus, king of Persia, a message was revealed to Daniel (also known as Belteshazzar). The message was trustworthy and concerned a great conflict. He understood it and had insight concerning the vision.

He told me, "Daniel, man highly regarded, understand the message that I'm about to relate to you. Stand up, because I've been sent to you.' When he spoke this statement to me, I stood there trembling.
