In Nehemiah 2:1 we read:
"And it came to pass in the month of Nissan, in the twentieth year of King Artaxerxes..."
What did the Jews in the postexilic era mean when they only mentioned the month of an event but not the specific day of that month? In Neh. 2:1, for example, only "month of Nissan" is mentioned (without a specific day). For the Jews during that time, did that mean something like "the event occurred in any day of Nisan" or did they implicitly mean the 1st or some other day?
Compared to us today: If we say that something happend in the month of March, it could be any day in March. Was that the same for Jews like Nehemiah?
In summary: What is the semantic of "in the month of Nissan" for the postexilic Jews? Thanks!
