आज तीर्थंकर ऋषभदेव भगवान का जन्म कल्याणक दिवस है

In Jainism, Rishabh Dev (ऋषभदेव) or Adinatha (आदिनाथ) (other names used: Riṣhabh, Riṣhabhanāth, Rushabh, Rushabhdev, Adinath or Adishwar or Kesariyaji; Sanskrit ṛṣabha meaning "best, most excellent") was the first of the 24 Tirthankara. He belonged to the House of Ikshwaku, which was also known as the "House of the Sun".

According to Jain beliefs, Rishabha was the first Tirthankar of the present age (Avasarpini). Because of this, he had the name of Ādināth - the original lord.
