Which can give the fix dating system.
Akbar insistence to equalize the Fasli calendar according to Islamic Lunar calendar accordingly with Hindu Samavat Calendar, thus he took 649 years from the Samavat Calendar year in order to make the Fasli year 963. Since then, the Fasli calendar proceeded according to the Samavat Calendar.
