# Why Does India Use One Time Zone Despite Its Wide East–West Span?

Sunrise and sunset can happen noticeably earlier in India’s northeast than in the west, yet the country uses a single official clock. I’m curious how that arrangement became the standard and how policymakers weigh having one national time against the daily difference across regions.

What considerations shaped **India’s single time zone**, and has changing it ever been seriously debated?
