In Jainism, both Nemi Nath (also known as Lord Neminatha) and Mahavir Swami (Lord Mahavira) are revered as Tirthankaras, spiritual teachers who have achieved liberation (moksha) and help guide others on the path.

Nemi Nath (Neminatha):

• He is the 22nd Tirthankara in the current time cycle (Avasarpini).
• He is believed to have lived many millennia before Mahavira, in a much earlier era.
• Neminatha was a cousin of Lord Krishna, according to Jain texts.

Mahavir Swami (Mahavira):

• He is the 24th and last Tirthankara of the current time cycle.
• He lived in the 6th century BCE (around 599–527 BCE).
• Mahavira revitalized and reorganized the Jain community and teachings.

Difference in Timeline:

• According to Jain scriptures, there is one Tirthankara (Parshvanath, the 23rd) between Neminatha and Mahavira.
• The exact number of years between Neminatha and Mahavira is not specified in commonly available Jain texts, but it is understood to be a vast period, spanning many thousands (or even millions) of years, as Jain cosmology describes very long time cycles.
• Neminatha's era is considered to be in the Dwapara Yuga, while Mahavira lived in the later part of the current era, closer to our time.

Summary:

• Nemi Nath is the 22nd Tirthankara, Mahavir Swami is the 24th.
• There are two Tirthankaras between them: Nemi Nath → Parshvanath (23rd) → Mahavir Swami (24th).
• The time difference between their lives is immense, covering many thousands or millions of years according to Jain tradition.
