Please explain this clear Bible error.

I posted the same question on Christianity.com, here was the reply:"Many scholars say that in the twentieth year of Asa's reign, the tribes of Benjamin and Judah separated from Israel, and the author of 1 Kings is counting from the separation, while the author of 2 Chronicles is counting from the beginning of Asa's reign.Not a contradiction."

Christians are wierd man.I posted that there, and then they entirely changed the subject about how secularists try to point out biblical errors, and they are wrong. They didn't even address the question. So, I asked again, and I'm waitin on it. I'll get back to you.

I recently came across this explanation, I just want to see what others think:* In 2 Chronicles 16:1, the phrase "the kingdom of Judah" was implied, yet omitted. Therefore, this verse can appear a little misleading. Here is another rendering of it: "In the 36th year (of the Kingdom of Judah), in the reign of Asa, Basha the King of Israel came up against Judah . . ." This verse is not indicating that it was the 36th year of Asa's reign. It tells us that it is the 36th year of the Kingdom of Judah. Incidentally, Baasha's death is not mentioned in 2 Chronicles and after chapter 16, he is not mentioned again.* 1 Kings 16:6-8 indicates that Baasha died in the 26th year of Asa's reign. It also tells us about Baasha's successors and more about Asa's reign and the timing of everything.
