The length and timing for when Baasha reigned over Israel is a place for much discussion. 1 Kings 15:33 says that he reign in the 3rd year of Asa and reigned 24 years and 2 Chronicles 16:8 mentions that Baasha son Elah reigned in the 26th year of Asa. However, 2 Chronicles 16:1 tells us that Baasha came up against Israel in the 36th year of Asa.
