1 Kings 12:32

And Jeroboam ordained a feast on the fifteenth day of the eighth month, like the feast that was in Judah, and he offered sacrifices on the altar; he made this offering in Bethel to sacrifice to the calves he had set up, and he installed priests in Bethel for the high places he had set up.

Note This feast was exactly one month after the annual Feast of Tabernacles in Judah; see Leviticus 23:34.
