Pandavas had to go on a 13-year exile after losing the game of dice to the Kauravas.
On the Pandava Panchami day, Arjuna appeared before the Kaurava Army to defend the kingdom of Virata.
Bhishma reminded Duryodhana that the Pandavas had completed the 12-year exile in forest and one year of disguise among people on the Kartik Shukla Panchami day.
