Parshwanath Jayanti (Parsushan) is the birth anniversary of Lord Parshvanath, the 23rd Tirthankar. The date varies by local Jain calendars and tradition (Shvetambar and Digambar often observe it on different days in January). For example, in 2024 Parshwanath Jayanti was observed on January 7. In 2025, the date can differ by temple or community, so please check your local sangh or temple calendar to know the exact day in your area.
