Whether India needs two time zones is a long-standing debate, balancing geographic efficiency against administrative simplicity. Proponents argue that with a 2,000 km east-west stretch causing a nearly two-hour sunrise difference, two zones would save electricity, improve health, and increase productivity in the Northeast, while opponents cite risks of railway chaos and administrative, BBC, Testbook, Quora, Shankar IAS Parliament, All Indians Matter.
Offices and business will start at morning hours with sunlight, meaning that artificial light is not as much required for a long time. A second time zone may help India share its time frame with its neighboring countries like Myanmar and Bangladesh for easy coordination at borders.
Why is it necessary for India to have three time zones?
One reason is, the time zones were originally designed to be on longitudes that were multiples of 15° from the Prime Meridian. We have two such longitudes within the mainland - the 75° East and the 90° East, both of which surround the central part of India, hence it makes sense to have three different time zones.
India uses only one time zone (even though it spans two geographical time zones) across the whole nation and all its territories, called Indian Standard Time (IST), which equates to UTC+05:30, i.e. five and a half hours ahead of Coordinated Universal Time (UTC).
Do India need to have more than one standard time?
Now to answer the question Yes, India requires multiple standard times due to a time difference of around 2 hours between the easternmost and westernmost portions of the country. India's huge longitudinal expanse is estimated to be around 30 degrees.

Why is it 5:30 in India and 12 in London?
Each degree of longitudinal corresponds to a difference of four minutes. This is because the Earth rotates 360 degrees in 24 hours, 1 degree in 4 minutes. The standard meridian of India is 82 degree 30E, and that of London is 0 degree. So when it is 12 noon in London, it is 5.30 pm in India.
Are there proposals for multiple time zones in India?
It proposed two time zones instead: five and a half hours ahead of GMT for one side of India, and six and a half hours for another, specifically what they've described as “extreme northeast regions,” including areas like Assam and Arunachal Pradesh.
For example, in New Delhi, India, they found themselves halfway between two meridians, and therefore decided to be 30 minutes between each, as opposed to adopting one time or the other. Also, even though India's expansive regions cross two time zones, all of India carries the same time. Even quirkier?
It was established during the International Meridian Conference held at Washington, D.C. in the United States. It was decided that India had two time zones: Calcutta (now Kolkata) would use the 90th meridian east and Bombay (now Mumbai) the 75th meridian east.
India does not follow daylight saving time as countries near the Equator do not experience high variations in daytime hours between seasons. (There is, however, a separate debate around the logic of sticking with only one time zone in a large country.)
UTC+14:00 is an identifier for a time offset from UTC of +14:00. This is the earliest time zone on Earth, meaning that areas in this zone are the first to see a new day, and therefore the first to enter a New Year.
Why did India choose to have one time zone instead of two?
Explanation. India has chosen to have one time zone (Indian Standard Time, IST) instead of two primarily for administrative convenience and national unity. A single time zone helps in synchronizing activities across the vast country, which can otherwise lead to confusion and inefficiency.
What is the biggest country with only one timezone?
The time in China follows a single standard time offset of UTC+08:00, where Beijing is located, even though the country spans five geographical time zones. It is the largest sovereign nation in the world that officially observes only one time zone.
MoaTrek Travel Tip: NZ time is 12 hours ahead of the UK and Europe. As a rule of thumb, add twelve hours to the time in New Zealand, then include an extra hour in either direction as a margin error. If you're calling New Zealand at 10 pm from the UK and at any time of the year, it's at least 9 am down under.
Russia, the largest country in the world by land area, spans across multiple time zones . Due to its vast size and geographical extent, Russia encompasses various time zones, each with its unique time difference from Coordinated Universal Time (UTC) .
Why is it 2pm in India when it is 8.30 am in London?
Explanation. The difference in time between India and London is primarily due to their positions relative to the Prime Meridian and the time zones they observe. India operates on Indian Standard Time (IST), which is UTC+5:30, while London operates on Greenwich Mean Time (GMT) or UTC+0 during standard time.
Beijing Standard Time is calculated and released from the National Time Service Centre in Shaanxi Province, which is geographically almost the centre of China. It sits eight hours ahead of GMT and was implemented throughout China in 1949 after Mao Zedong decreed that it would aid 'national unity'.
India uses one time zone (IST) for the entire country. Therefore, watches showing the same time is due to the standard time system despite different local sunrise times.
Which country has the highest time difference with India?
The country furthest behind India in time is the US Minor Outlying Island of Baker Island, which is 17.5 hours behind Indian Standard Time (IST), at UTC-12. The time difference is not a solid number, as some countries like India have an offset of 30 minutes.
Why is there a time difference of about 5 hours between India and London?
India follows Indian Standard Time (IST = UTC+5:30) based on 82.5° East longitude, while London follows Greenwich Mean Time (GMT = UTC+0) based on 0° longitude. Since Earth rotates 15° every hour, the 82.5° longitudinal difference creates a 5.5-hour difference.
