I apologize in advance if I'm posting this in the wrong forum - I'm teachable!
I'm getting stuck up on dates and just need a little direction/clarification. Thank you in advance for the help.
Subject: Book of Obadiah, Prophet Obadiah
Advanced Timeline tool shows "Book of Obadiah written circa 400 BC" (see Figure-1)

Bible Books Explorer shows composite dates for the book of Obadiah ranging from 900 BC - 840 BC (See Figure-2)
Can someone help me understand the discrepancy or is it as simple that the Bible Books Explorer is estimated the dates for the events of Obadiah?
