Bhauma Pradosham

Bhauma Pradosham is the Pradosha Vrata (Trayodashi twilight worship of Shiva) falling on a Tuesday, ruled by Mangal (Mars), traditionally observed for relief from debt and Mangal dosha. When this occurrence is also the Gauna (secondary) Pradosham day, the rare case where Trayodashi falls across two days, it is shown as "Bhauma Pradosham (Gauna)".
