Why Nepal Is 15 Minutes Off the World

A clock in Kathmandu reads 12:45 when London hits 7:00. The rest of the world snaps to the hour or, sometimes, the half-hour. Nepal sits at +5:45, fifteen minutes ahead of India and a quarter-hour off the rest of South Asia. It is the only country at that exact offset.

The choice is geographic and a little stubborn. Nepal's official time meridian runs through Gaurishankar peak, about 100 kilometers east of Kathmandu. That meridian sits at roughly 86°15' east longitude, which translates to UTC +5:45 if you do the arithmetic on the sun. The country picked the mountain, then asked the clocks to follow.

Nepal didn't always do this. From 1956 until 1986 it ran on Indian Standard Time, +5:30. The split came partly from a desire to mark the country as separate from its much larger neighbor — a clock difference is the cheapest possible flag. The change was announced and adopted with little fanfare, and the new offset stuck.

The planet has dozens of these quirks. India runs the entire subcontinent on a single half-hour offset. Iran is +3:30. Newfoundland sits at -3:30 and refuses to budge. Chatham Islands, off New Zealand, run +12:45. Each one is a small story about geography arguing with administration.

The original sin was the railway. Before the 1884 International Meridian Conference in Washington, every town kept its own solar time, and timetables were unprintable. The conference picked Greenwich as zero and divided the world into 24 hour-wide slices. Most governments rounded to the nearest line. A few — Nepal, India, Iran — looked at the sun and decided that 30 or 45 minutes was the honest answer.
