It is the 1st of Tishrei - what we call Rosh Hashannah.

Ezra and Nehemiah join hands and arrange a huge gathering in which the Torah is brought out of the Temple and read and translated. The text emphasizes that Ezra took special measures to have the people understand the sacred text - he translated and explained it - and that the people did indeed comprehend. This is the beginning, the first step of Torah Study as a key tool of Jewish life and continuity.
