'Months' in the Bible

It was at this [critical] time that Moses was born; and he was lovely in the sight of God, and for three months he was nourished in his father’s house.

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

And he went into the synagogue and for three months spoke boldly, reasoning and arguing and persuading them about the kingdom of God.

And he stayed three months, and when a plot was formed against him by the Jews as he was about to set sail for Syria, he decided to return through Macedonia (northern Greece).

At the end of three months we set sail on a ship which had wintered at the island, an Alexandrian ship with the Twin Brothers [Castor and Pollux] as its figurehead.
