Dennis the Short (470-544 CE) or Dionysius Exiguus, a Scythian monk who worked in Rome, came up with the idea of dating everything from the birth of Christ, instead of the Roman counsels who had held office. In 525 CE, he developed his Christocentric calendar, but he was off by a few years in his calculations, since Jesus may have lived from 6 BCE-26 CE. His dating system was known as Anno Domini, the year of Our Lord. This AD system did not become popular until the Carolingian Reform of the 9th ninth century and the promulgation of the Gregorian calendar in the 16th century. Since then, all world events have centered on the birth of Christ. At the 2000 millennium year celebrations even non-Christian countries such as China and India celebrated the 2000th anniversary of the birth of Jesus Christ. In the twentieth century, Jewish and Christian scholars adopted the term CE, or Common Era, showing a neutral stance towards Christ. Now practically every country dates things from the birth of Christ, whether they consider themselves Christian or not. 2018 CE means 2018 years since the birth of Christ, the Common Era. The time before Christ is called BC, before the Common Era, BCE.

The official institution of Purim (Esth 9:20-9:23)
“Mordecai recorded these things. He sent letters to all the Jews who were in all the provinces of King Artaxerxes, both near and far. He enjoined them that they should keep the fourteenth day of the month of Adar and also the fifteenth day of the same month, year by year. These are the days on which the Jews gained relief from their enemies. This is the month that had been turned for them from sorrow into gladness, and from mourning into a holiday. They should make them days of feasting and gladness, days for sending gifts of food to one another, and presents to the poor. Thus the Jews adopted as a custom what they had begun to do, as Mordecai had written to them.”
Mordecai put in a decree for the Jews of the Persian kingdom, a custom that they had already started. This became known as Purim. Each year they should remember what happened to them on the 14th and 15th of Adar. They should exchange food gifts and give to the poor. They were to remember that on this day that they turned from sorrow to gladness and from mourning to feasting. In modern day Judaism, this has become a big holiday eating and drinking for Conservative and Orthodox Jews, much like a Halloween feast. Children dress up and exchange treats. They read the Book of Esther, while booing Haman and cheering Mordecai.
Esther becomes the new queen (Esth 2:15-2:18)
“When the turn came for Esther daughter of Abihail, the uncle of Mordecai who had adopted her as his own daughter, to go in to the king, she asked for nothing except what Hegai the king’s eunuch who had charge of the women, advised. Now Esther was admired by all as she found favor in the eyes of all who saw her. When Esther was taken to King Artaxerxes into his royal palace in the twelfth month, which is Adar, in the seventh year of his reign, the king loved Esther more than all the other women. She won his favor and grace over all the virgins. He set the royal diadem crown on her head as she became queen. Then the king gave a great banquet to all his friends and officials lasting seven days to celebrate his marriage to Esther. He also granted a holiday remission of taxes to all the provinces under his rule. He gave gifts with royal liberality.”
Esther finally got her turn to audition with the king. She simply followed the advice of the eunuch Hegai. This was now the 7th year of the king’s rule, around 458 BCE. The original feast where the argument took place about Queen Vashti was in the 3rd year of his rule. Now after 4 years, Vashti was gone, without any mention of what happened to her. Now King Artaxerxes was smitten with Esther as he said that she was the one, since he loved her more than all the others. He immediately gave her the crown as she became Queen Esther. He gave a big wedding banquet in Esther’s honor. He also gave a tax holiday. Now that is a real holiday. He also gave gifts, which seems the opposite of most weddings where the bride and groom get the gifts. There is no specific mention of a wedding ceremony, but it might be presumed if they had a wedding banquet. There seems to be no problem about a Jewish woman marrying a non-Jewish person as there was in Ezra, chapters 9-10, and Nehemiah, chapter 10, which would have been about the same time frame. That prohibition was more about Jewish men marrying non-Jewish women.
