Only a (very) partial answer, but סדר הדורות puts it in the year 2921 from Creation. (Top of right column). Technically it states that his rule started on that year, but then again, he wasn't king very long.

Actual quote:

אבשלום מלך ב"א תתקכ"א, שלש שנים קודם מות אביו

My translation:

Avshalom ruled in the year 2921 [to Creation], three years before his father's death.
