'Today' in the Bible

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.

And Esther in answer said, If it seems good to the king, let the king and Haman come today to the feast which I have made ready for him.

Then Esther said, If it is the king's pleasure, let authority be given to the Jews in Shushan to do tomorrow as has been done today, and let orders be given for the hanging of Haman's ten sons.
