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.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

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).

Why people convert Bangalore to PDT time

Scheduling a call from Bangalore to PDT: a 10:00 AM start in Bangalore lands at 9:30 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -12h 30m gap: Bangalore and PDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PDT is 8:30 PM in Bangalore.
Keeping family and friends in sync: knowing that 8:00 PM in Bangalore is 7:30 AM in PDT makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -12h 30m gap is not.
With a -12h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week Bangalore takes the early slot, the next week PDT does.

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.

About PDT (Pacific Daylight Time)

Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.

Best time to call between Bangalore and PDT

With a -12h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. PDT opens at 9:00 AM PDT, which is 8:30 PM in Bangalore, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Bangalore and PDT have no shared working hours because of the -12h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Bangalore is 12 hours 30 minutes behind PDT (IST UTC+05:30 → PDT UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
