Etymology and references in literature
Hindu literature is replete with references of terms like Dolotsava and Dola Yatra. Shri Garga Samhita, a Vaishnav text has reference to Dolotsava of Shri Krishna in the month of Chaitra.

The Sanskrit word Dola means a swing, while utsava means a festival or a feast. Hence, Dolotsava literally means swing festival or swing feast and refers to religious service of swinging the idol of a deity on a swing.

Similarly, word Dola Yatra is compound of two Sanskrit words: Dola and yatra . Yatra refers to procession and thus Dola yatra refers to swing procession.
