According to Jain tradition, there is a time difference of 84,000 years between the nirvana (liberation) of Lord Neminath (the 22nd Tirthankara) and Lord Mahavir Swami (the 24th Tirthankara).

Here is a summary based on Jain scriptures:

• Lord Neminath (22nd Tirthankara) attained nirvana on Mount Girnar.
• Lord Parshvanath (23rd Tirthankara) was born 84,000 years after Neminath’s nirvana.
• Lord Mahavir Swami (24th Tirthankara) was born 250 years after Lord Parshvanath’s nirvana.

Therefore, the time between Lord Neminath and Lord Mahavir Swami is 84,250 years, according to Jain historical calculations.
