'Year' in the Bible

But when he reached the age of forty, it came into his heart to visit his brothers, the sons of Israel.

and when he found him, he brought him back to Antioch. For an entire year they met [with others] in the church and instructed large numbers; and it was in Antioch that the disciples were first called Christians.

So he settled there for a year and six months, teaching them the word of God [concerning eternal salvation through faith in Christ].
