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).

Understanding the -2h Gap: MDT vs PST

MDT runs on Mountain Daylight Time (MDT) at UTC-06:00. PST runs on Pacific Standard Time (PST) at UTC-08:00. That puts MDT 2 hours behind PST — a difference of -2h at the current offsets.

In practice, when it is 9:00 AM in MDT it is 7:00 AM in PST. Midnight in MDT is 10:00 PM in PST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MDT to PST time

Scheduling a call from MDT to PST: a 10:00 AM start in MDT lands at 8:00 AM in PST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both MDT and PST are inside the 9-to-5 working day between 11:00 AM and 5:00 PM MDT time (9:00 AM–3:00 PM PST). That is roughly 6 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in MDT is 6:00 PM in PST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a -2h gap is not.
Block 11:00 AM–5:00 PM MDT as the recurring meeting window if you work primarily from MDT and need PST colleagues present.

About MDT (Mountain Daylight Time)

Mountain Daylight Time (MDT) is observed during summer months in the Mountain Time Zone, except in Arizona which stays on MST year-round. MDT aligns with Central Standard Time (CST) at UTC-06:00.

About PST (Pacific Standard Time)

Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.

Best time to call between MDT and PST

Both MDT and PST sit inside the 9 AM – 5 PM working day between 11:00 AM–5:00 PM MDT, which is 9:00 AM–3:00 PM PST. That gives roughly 6 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

MDT and PST share 6 hours of working-hours overlap (11:00 AM–5:00 PM MDT), so scheduling a live meeting is straightforward.

MDT is 2 hours behind PST (MDT UTC-06:00 → PST UTC-08:00). The shared working window is 11:00 AM–5:00 PM MDT. Remember to re-check around daylight-saving transitions.
