    1. Indian Standard Time (IST) is calculated from the 82.5°E longitude, which passes near Allahabad, in central India. This meridian was chosen to ensure a uniform time standard across the country, despite India’s wide longitudinal spread. IST is 5 hours 30 minutes ahead of GMT. Using this reference point, India avoids using multiple local times, making timekeeping consistent across regions, from Gujarat in the west to Arunachal Pradesh in the east.
