Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Understanding the +5h 30m Gap: UTC vs Delhi

UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. Delhi runs on India Standard Time (IST) at UTC+05:30. That puts UTC 5 hours 30 minutes ahead of Delhi — a difference of +5h 30m at the current offsets.

In practice, when it is 9:00 AM in UTC it is 2:30 PM in Delhi. Midnight in UTC is 5:30 AM in Delhi. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert UTC to Delhi time

Scheduling a call from UTC to Delhi: a 10:00 AM start in UTC lands at 3:30 PM in Delhi, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both UTC and Delhi are inside the 9-to-5 working day between 9:00 AM and 11:30 AM UTC time (2:30 PM–5:00 PM IST). That is roughly 2 hours 30 minutes of usable overlap.
Booking travel or deliveries: tracking Delhi local time against UTC keeps pickup windows and arrival estimates honest across the +5h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM UTC" is unambiguous; "3 PM" across a +5h 30m gap is not.
Block 9:00 AM–11:30 AM UTC as the recurring meeting window if you work primarily from UTC and need Delhi colleagues present.

About UTC (Coordinated Universal Time)

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.

About IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.

Best time to call between UTC and Delhi

Both UTC and Delhi sit inside the 9 AM – 5 PM working day between 9:00 AM–11:30 AM UTC, which is 2:30 PM–5:00 PM IST. That gives roughly 2 hours and 30 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

UTC and Delhi overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.

UTC is 5 hours 30 minutes ahead of Delhi (UTC UTC+00:00 → IST UTC+05:30). The shared working window is 9:00 AM–11:30 AM UTC. Remember to re-check around daylight-saving transitions.
