According to the traditional Hindu calendar, this Besha is observed on Kartik Sukla Trayodasi Tithi (the 13th day of the bright fortnight in Karttika).
This Besha or attire of Sri Jagannath, Sri Balabhadra and Devi Subhadra is also known as Tribikram Besha. The term Tribikram denotes the Vamana Avatar of Lord Vishnu. In the Vamana Avatar, Shree Vishnu had taken over the whole creation by his three steps. These three steps marked his bikram or power. The devotees get a chance to witness the power of the three deities of this temple through this Besha.
Like the Thiakia Besha held on Kartik Panchuka Ekadasi, kewda flowers made up of gold play a key role in this Besha. The name Adakia means kewda flower placed at a side. Real kewda flowers are not used during this Besha. Instead of real ones, Kewda flowers made up of gold are attached to the sides of Trimundi crown of the deities. Gold Chandrikas are also added to the crown of the deities.
During the Adakia Besha, Sri Jagannath and Sri Balabhadra adorn hands and feet made up of gold like the famous Suna Besha. Shree Jagannath holds gold conch in left hand and golden chakra in his right hand. Sri Balabhadra holds a Hala (plough) and a Musala (pestle) in his two hands. Devi Subhadra is decorated with gold ornaments.
