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).

Everything You Need to Know About MSK and CAT Time

MSK runs on Moscow Standard Time (MSK) at UTC+03:00. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts MSK 1 hour behind CAT — a difference of -1h at the current offsets.

In practice, when it is 9:00 AM in MSK it is 8:00 AM in CAT. Midnight in MSK is 11:00 PM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MSK to CAT time

Scheduling a call from MSK to CAT: a 10:00 AM start in MSK lands at 9:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both MSK and CAT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM MSK time (9:00 AM–4:00 PM CAT). That is roughly 7 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in MSK is 7:00 PM in CAT makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM MSK" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM MSK as the recurring meeting window if you work primarily from MSK and need CAT colleagues present.

About MSK (Moscow Standard Time)

Moscow Standard Time (MSK) is the time zone used in Moscow, St. Petersburg, and much of western Russia. Russia abolished DST in 2011, so MSK is observed year-round. MSK is also the reference time for Russian railways – all train schedules in Russia are given in Moscow Time regardless of the actual local time zone.

About CAT (Central Africa Time)

Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.

Best time to call between MSK and CAT

Both MSK and CAT sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM MSK, which is 9:00 AM–4:00 PM CAT. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

MSK and CAT share 7 hours of working-hours overlap (10:00 AM–5:00 PM MSK), so scheduling a live meeting is straightforward.

MSK is 1 hour behind CAT (MSK UTC+03:00 → CAT UTC+02:00). The shared working window is 10:00 AM–5:00 PM MSK. Remember to re-check around daylight-saving transitions.
