'Month' in the Bible

So Esther was taken in to King Ahasuerus in his house in the tenth month, which is the month Tebeth, in the seventh year of his rule.

In the first month, the month Nisan, in the twelfth year of King Ahasuerus, from day to day and from month to month they went on looking for a sign given by Pur (that is chance) before Haman, till the sign came out for the thirteenth day of the twelfth month, the month Adar.

Then on the thirteenth day of the first month, the king's scribes were sent for, and they put in writing Haman's orders to all the king's captains and the rulers of every division of his kingdom and the chiefs of every people: for every division of the kingdom in the writing commonly used there, and to every people in the language which was theirs; it was signed in the name of King Ahasuerus and stamped with the king's ring.

And letters were sent by the runners into every division of the kingdom ordering the death and destruction of all Jews, young and old, little children and women, on the same day, even the thirteenth day of the twelfth month, the month Adar, and the taking of all their goods by force.

Then at that time, on the twenty-third day of the third month, which is the month Sivan, the king's scribes were sent for; and everything ordered by Mordecai was put in writing and sent to the Jews and the captains and the rulers and the chiefs of all the divisions of the kingdom from India to Ethiopia, a hundred and twenty-seven divisions, to every division in the writing commonly used there, and to every people in their language, and to the Jews in their writing and their language.

On one day in every division of the kingdom of Ahasuerus, that is, on the thirteenth day of the twelfth month, the month Adar.

Now on the thirteenth day of the twelfth month, which is the month Adar, when the time came for the king's order to be put into effect, on the very day when the haters of the Jews had been hoping to have rule over them; though the opposite had come about, and the Jews had rule over their haters;

For the Jews who were in Shushan came together again on the fourteenth day of the month Adar and put to death three hundred men in Shushan; but they put not a hand on their goods.

This they did on the thirteenth day of the month Adar; and on the fourteenth day of the same month they took their rest, and made it a day of feasting and joy.

But the Jews in Shushan came together on the thirteenth and on the fourteenth day of the month; and on the fifteenth day they took their rest, and made it a day of feasting and joy.

So the Jews of the country places living in unwalled towns make the fourteenth day of the month Adar a day of feasting and joy and a good day, a day for sending offerings one to another.

Ordering them to keep the fourteenth day of the month Adar and the fifteenth day of the same month, every year,

As days on which the Jews had rest from their haters, and the month which for them was turned from sorrow to joy, and from weeping to a good day: and that they were to keep them as days of feasting and joy, of sending offerings to one another and good things to the poor.
