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 Iran to Melbourne time

Scheduling a call from Iran to Melbourne: a 10:00 AM start in Iran lands at 4:30 PM in Melbourne, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Iran and Melbourne are inside the 9-to-5 working day between 9:00 AM and 10:30 AM IRST time (3:30 PM–5:00 PM AEST). That is roughly 1 hours 30 minutes of usable overlap.
Coordinating a Iran-based team with Melbourne contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a +6h 30m gap is not.
Block 9:00 AM–10:30 AM IRST as the recurring meeting window if you work primarily from Iran and need Melbourne colleagues present.
Melbourne: Clocks spring forward on Sat, Oct 3, 2026. Any meeting series spanning that date will shift by an hour in local time.
