I’m not sure what you’re referring to by “this.” If you mean the origins of Jainism:

• Jainism as a tradition is traced to the teachings of the Tirthankaras, with Mahavira (the 24th Tirthankara) traditionally dated to around 599–527 BCE. Different traditions may give slightly different dates, but that general period is widely accepted by Jain scholars.

If you meant something specific like:

• a Jain festival or prayer (e.g., a stotra or sutra)
• a project or website you’re asking about
• a particular event or program

please clarify which one you have in mind, and I’ll give you the exact dates and details.
