Deo lies in the southern part of Bihar, in the Magadh region, on the plains that extend southwards towards the Chhotanagpur plateau. It is situated in Aurangabad district, which borders Jharkhand to the south. The terrain around Deo is largely agricultural, with paddy and wheat as the principal crops, supported by canal irrigation linked to the Sone river system.
Deo functions as the headquarters of the Deo CD block, one of the administrative blocks of Aurangabad district. The block contains a number of revenue villages and gram panchayats, and is administered through the standard tier of block development office, circle office and panchayati raj institutions used across Bihar. For parliamentary representation, the area falls within the Aurangabad Lok Sabha constituency.
The town's central cultural landmark is the Deo Surya Mandir, a temple dedicated to the Sun god. The shrine is unusual for facing west rather than the conventional east, a feature that is widely cited in local tradition. The temple is constructed in a style associated with Nagara architecture and is one of the principal Sun temples in eastern India, alongside Konark in Odisha.
During the Chhath festival, observed twice a year in the months of Kartik (October–November) and Chaitra (March–April), the temple complex and the adjoining tank become a major pilgrimage site, attracting devotees from across Bihar, Jharkhand, Uttar Pradesh and beyond.
The local economy of Deo is primarily agrarian, complemented by small-scale trade and services that support the surrounding rural population. Pilgrim traffic, especially during Chhath, contributes seasonally to the local economy through lodging, transport, food vending and ritual supplies.
Deo is connected by road to Aurangabad town, the district headquarters, which lies on the Grand Trunk Road (National Highway 19, formerly NH 2). Aurangabad in turn provides onward connectivity to Patna, Gaya, Dhanbad and Varanasi. The nearest major railway connections are accessed via stations on the Patna–Gaya and Grand Chord lines passing through the district.
The cultural life of Deo is closely tied to the Surya Mandir and to the Chhath observance. A major fair is held in the town around Chhath, and the temple's legends are linked to local royal traditions associated with the erstwhile Deo estate, whose ruling family historically patronised the shrine.
