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).

Comparing Time Zones: COT and SAST

COT runs on Colombia Time (COT) at UTC-05:00. SAST runs on South Africa Standard Time (SAST) at UTC+02:00. That puts COT 7 hours ahead of SAST — a difference of +7h at the current offsets.

In practice, when it is 9:00 AM in COT it is 4:00 PM in SAST. Midnight in COT is 7:00 AM in SAST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert COT to SAST time

Scheduling a call from COT to SAST: a 10:00 AM start in COT lands at 5:00 PM in SAST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both COT and SAST are inside the 9-to-5 working day between 9:00 AM and 10:00 AM COT time (4:00 PM–5:00 PM SAST). That is roughly 1 hours of usable overlap.
Coordinating a COT-based team with SAST 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 COT" is unambiguous; "3 PM" across a +7h gap is not.
Block 9:00 AM–10:00 AM COT as the recurring meeting window if you work primarily from COT and need SAST colleagues present.

About COT (Colombia Time)

Colombia Time (COT) is used throughout Colombia. Colombia does not observe daylight saving time. COT shares the same offset as EST (UTC-05:00). Bogotá, the capital, is one of the largest cities in South America.

About SAST (South Africa Standard Time)

South Africa Standard Time (SAST) is used in South Africa, Lesotho, and Eswatini. SAST does not observe daylight saving time. Johannesburg and Cape Town are major economic hubs in Africa.

Best time to call between COT and SAST

Both COT and SAST sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM COT, which is 4:00 PM–5:00 PM SAST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

COT and SAST overlap for only 60 minutes (9:00 AM–10:00 AM COT), so meetings have to be booked precisely.

COT is 7 hours ahead of SAST (COT UTC-05:00 → SAST UTC+02:00). The shared working window is 9:00 AM–10:00 AM COT. Remember to re-check around daylight-saving transitions.
