Mathura, the birthplace of Lord Krishna, where his parents lived in captivity of the evil Kansa and he as a young boy came and vanquished his maternal uncle Kansa to ascend the throne and free his parents, celebrates Janmashtami with great enthusiasm. The main celebrations are performed at the Dwarkadhish temple, Mathura in the form of Jhulanotsava and the Ghatas during the entire month of Shravan. The ghatas are a unique feature of the month long celebrations. During the ghatas of a particular colour the whole temple is covered with decoration in the same colour. Even the Lord dresses up in the same colour. The twin cities of Mathura-Vrindavan takes on a festive look and spirit of devotion runs high among the people. It was on the banks of the Yamuna river where Lord Krishna played during his childhood and indulged in pranks and tricks with his friends and the gopies. There are about 400 temples dedicated to Lord Krishna in this sacred city and the major festivities are held at the Banke Bihari, Rangaji, Shri Krishna Balram temple and Gopinath temple. The Raslila of Braj is thematically the basis of many performing arts.

Lord Krishna was born in the DuaparYug which came just before the Kal Yug and Janamasthami, his birthday falls on the Ashtami Paksh or the 8th day of the new moon fortnight in the month of Bhadra some time in July or August. The Jhankis ( tableaux) depicting many significant scenes from Lord Krishna's life are the intrinsic part of Janmasthami. Devotees also make beautiful Jhulans (Cradles) for the baby Krishna. In some parts of India, young men break the Matkas (Earthen Pots) filled with butter and curds. The most important tableux is that of baby Krishna. A idol of baby Krishna is placed on a cradle, which is rocked to recreate scenes from Krishna's infancy. The devotees believe that anyone who makes a wish and while rocking the cradle in which the Lord is, his or her wish will be granted on this day. Other popular Jhankis are Kaaliya Mardan(vanquishing the black snake Kali Nag), Kansha vadha ( Killing Kansha) and lifting the Govardhan Parbhat.

In Brindavan, every year the Raasleelas or the folk theatre acting out Krishnas Lifes stories begin much before the Janmasthami day. These Raasleelas are staged by professional drama troupes or even young children. These dramas characterised by colourful costumes and equally colourful backgrounds. Raasleelas are usually accompanied by musicians and are very popular among the people. The language spoken by the actors and the actresses is the Brajbhasha but sometimes Hindi is also used.
