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 Chile to Riyadh time

Scheduling a call from Chile to Riyadh: a 10:00 AM start in Chile lands at 4:00 PM in Riyadh, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Chile and Riyadh are inside the 9-to-5 working day between 9:00 AM and 11:00 AM CLST time (3:00 PM–5:00 PM AST). That is roughly 2 hours of usable overlap.
Coordinating a Chile-based team with Riyadh 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 CLST" is unambiguous; "3 PM" across a +6h gap is not.
Block 9:00 AM–11:00 AM CLST as the recurring meeting window if you work primarily from Chile and need Riyadh colleagues present.
Chile: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +6h gap.

About CLT (Chile Standard Time)

Chile Standard Time (CLT) is the standard time in Chile. During summer months (October to March), Chile switches to Chile Summer Time (CLST, UTC-03:00). Chile is the longest north-south country in the world.

About AST (Arabia Standard Time)

Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen. None of these countries observes daylight saving time, so the offset never changes. The abbreviation collides with Atlantic Standard Time (UTC-04:00) used in eastern Canada and the Caribbean; this page covers the Arabian peninsula meaning. Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.

Best time to call between Chile and Riyadh

Both Chile and Riyadh sit inside the 9 AM – 5 PM working day between 9:00 AM–11:00 AM CLST, which is 3:00 PM–5:00 PM AST. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

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

Chile is 6 hours ahead of Riyadh (CLST UTC-03:00 → AST UTC+03:00). The shared working window is 9:00 AM–11:00 AM CLST. Remember to re-check around daylight-saving transitions.
