For example, 9:00 AM in Siwān is 11:30 PM in New York the previous day during Eastern Standard Time, 12:30 AM during Eastern Daylight Time, 3:30 AM in London during GMT, 4:30 AM during BST, and 7:30 AM in Dubai, which shows why Gulf-region calls are much easier than US East Coast morning coordination.
Export or share the selected time range: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link so everyone receives the meeting in their own local time. This is useful for sending a school admission interview slot, arranging a logistics handoff with a Dubai-based freight partner, or sharing a recurring support window with distributed teams without manually converting IST for each participant.
About Siwān Time Zone
Siwān uses the Asia/Kolkata time zone, which is the standard IANA time zone identifier for most of India. Its standard offset is UTC+05:30, meaning local time in Siwān is five hours and thirty minutes ahead of Coordinated Universal Time. India is one of the world’s large countries that uses a single national time zone, so Siwān follows the same clock as Delhi, Mumbai, Kolkata, Bengaluru, and Chennai.
Siwān does not observe daylight saving time, so its UTC offset stays at UTC+05:30 all year. This makes scheduling more predictable than in countries where clocks shift in March and October or November. While London changes between UTC+0 and UTC+1 and New York changes between UTC-5 and UTC-4, Siwān remains fixed, so the time difference with those cities changes seasonally even though Siwān itself never changes.
Geographically, Siwān is in the state of Bihar in eastern India, near the broader North Indian and Gangetic plain region. Compared with neighboring international time zones, Siwān is 30 minutes behind Nepal Time (UTC+05:45), 30 minutes ahead of Pakistan Standard Time (UTC+05:00), and 1 hour ahead of Bangladesh Standard Time? No—Bangladesh is UTC+06:00, so Siwān is actually 30 minutes behind Bangladesh. These half-hour and quarter-hour regional differences are important for cross-border transport planning, embassy coordination, and multinational customer support schedules.
Siwān City Details
Siwān is a city in Bihar, India, with a population of 119,181, making it a significant urban center in its district rather than a small rural locality. Its coordinates are 26.22096° N, 84.35609° E, placing it in northern India within the fertile plains that connect Bihar to major population and trade corridors across eastern Uttar Pradesh and the rest of the Gangetic belt.
The local currency is the Indian Rupee (INR), which is the standard currency used for retail payments, rail bookings, domestic flights, mobile services, and business transactions throughout India. The country dialing code is +91, so international callers placing a call to Siwān from the US, UK, UAE, or elsewhere must use India’s country code before the local number.
For practical travel and business use, these details matter when booking hotels, confirming train tickets, arranging remittances, or contacting schools, hospitals, and local businesses. If you are scheduling services from abroad, combining the +91 dialing code with the fixed UTC+05:30 time zone helps avoid missed calls outside local working hours, which are typically around 10:00 AM to 6:00 PM IST for many offices.
Time Differences from Siwān
Siwān is 10 hours 30 minutes ahead of New York during Eastern Standard Time (EST, UTC-5) and 9 hours 30 minutes ahead during Eastern Daylight Time (EDT, UTC-4). That means when it’s 9:00 AM in Siwān, it’s 10:30 PM the previous day in New York during EST, or 11:30 PM the previous day during EDT. For US coordination, late afternoon in Siwān often works better than morning because it overlaps with early US business hours.
Siwān is 5 hours 30 minutes ahead of London during Greenwich Mean Time (GMT, UTC+0) and 4 hours 30 minutes ahead during British Summer Time (BST, UTC+1). So 9:00 AM in Siwān is 3:30 AM in London during GMT and 4:30 AM during BST. For UK-India business calls, a practical overlap is often 1:30 PM to 5:30 PM in Siwān, which corresponds to 8:00 AM to 12:00 PM in London during GMT.
Siwān is 3 hours 30 minutes behind Tokyo, because Japan Standard Time is UTC+09:00 year-round. If it is 9:00 AM in Siwān, it is 12:30 PM in Tokyo, which makes same-day coordination relatively easy for manufacturing, sourcing, and academic communication across Asia.
Siwān is 4 hours 30 minutes behind Sydney during Australian Eastern Standard Time (AEST, UTC+10) and 5 hours 30 minutes behind during Australian Eastern Daylight Time (AEDT, UTC+11). So 9:00 AM in Siwān equals 1:30 PM in Sydney during AEST and 2:30 PM during AEDT. This creates a useful daytime overlap for education agents, migration consultants, and support teams serving both India and Australia.
Siwān is 1 hour 30 minutes ahead of Dubai, since Gulf Standard Time is UTC+04:00 all year and does not use daylight saving time. That means when it’s 9:00 AM in Siwān, it’s 7:30 AM in Dubai. This is one of the easiest international pairings for trade, freight, construction staffing, and family communication because both locations share substantial same-day working hours.
Frequently Asked Questions
What time zone is Siwān in?
Siwān is in the Asia/Kolkata time zone, which is the official IANA time zone used across India. Its local time is UTC+05:30, the same as cities such as Delhi, Mumbai, Kolkata, Patna, and Bengaluru, so there is no separate regional time for Siwān.
Does Siwān observe daylight saving time?
No, Siwān does not observe daylight saving time. Like the rest of India, it stays on UTC+05:30 year-round, so the local clock does not move forward in spring or backward in autumn. This makes scheduling with Siwān consistent, although the time difference with cities like New York and London changes when those places switch between standard time and daylight saving time.
What is the time difference between Siwān and New York?
The difference depends on the season in New York because Siwān stays fixed while New York changes clocks. Siwān is 10 hours 30 minutes ahead of New York during EST and 9 hours 30 minutes ahead during EDT. For example, 8:00 PM in Siwān is 9:30 AM in New York during EST or 10:30 AM during EDT, which is often a better overlap than early morning in India.
What is the best time to call Siwān from the US?
For callers in the US, the best time usually depends on whether you are calling from the East Coast or West Coast and whether you need business-hour contact in Siwān. A practical window from the US East Coast is often 8:00 AM to 10:00 AM New York time, which corresponds to 5:30 PM to 7:30 PM in Siwān during EDT; during EST, 8:00 AM New York is 6:30 PM in Siwān. If you are calling family rather than an office, slightly later evening in Siwān may still be acceptable, but for banks, schools, or government offices you should target 10:00 AM to 6:00 PM IST.
What is the best time to call Siwān from the UK?
For UK callers, the most convenient overlap is usually the UK morning and Siwān afternoon. During GMT, 9:00 AM in London is 2:30 PM in Siwān, while during BST, 9:00 AM in London is 1:30 PM in Siwān. That makes late morning in the UK a good choice for speaking with businesses, schools, or service providers in Siwān before local offices close.
What is the UTC offset for Siwān?
Siwān’s UTC offset is UTC+05:30 throughout the entire year. There is no seasonal shift, so if it is 12:00 PM UTC, it is always 5:30 PM in Siwān. This fixed offset is especially helpful for recurring meetings, airline planning, and software systems that need stable time conversion rules.
What currency does Siwān use?
Siwān uses the Indian Rupee (INR), the national currency of India. Prices for hotels, transport, groceries, mobile recharges, and local services are quoted in INR, and international visitors usually pay through Indian bank cards, UPI-supported apps where available, cash withdrawals, or currency exchange into rupees. If you are sending money to someone in Siwān, remittance services will typically convert your home currency into INR before delivery.
Is Siwān on the same time as the rest of India?
Yes, Siwān follows the same time as all major Indian cities because India uses one national standard time. Whether you compare Siwān with Patna, Delhi, Mumbai, Chennai, or Kolkata, the clock is the same: Asia/Kolkata, UTC+05:30. This is useful for domestic travel planning, train schedules, and nationwide business operations because there is no internal time-zone change within India.
