UTC Offsets
UTC Offset Time Zones
Browse time zones by their UTC offset — a simple number showing how many hours ahead or behind a place is from the global reference point. Great for quick time calculations.
Convert Between Offsets
Select any UTC offset time zones and instantly see the current time in each. Helpful when you know the offset but not the city name.

Compare times across different zones and explore any moment in the day
Click the up arrow to make any timezone your reference point. All time differences will be calculated from this base.
Drag the grip icon to rearrange timezones in your preferred order. Base timezone cannot be dragged but others can be reordered.
Click the X button to delete a timezone from your comparison. Cannot remove if it's the only one left.
Use the slider below to explore different times. Drag to see how times change across all zones simultaneously.
View hour tiles showing the full 24-hour day. Use the time slider to navigate through different hours. Darker tiles indicate nighttime hours.
Switch between 12h/24h format and choose "Each" to set different formats per timezone or "All" to apply the same format to all zones.
💡 Pro tip: Add more timezones using the search above, then set one as your base to see all time differences at a glance!

Why UTC Offsets Matter
Offset-based time zones give you a straightforward way to think about time differences without memorizing city names or complicated rules.
How UTC Offsets Work
The simplest way to express time differences
A UTC offset is just a number — positive or negative — that tells you how far a place's local time is from Coordinated Universal Time. If you're at UTC+3, your clock shows 3 hours later than UTC. At UTC-7, it's 7 hours earlier.
This makes mental math easy. Need to call someone at UTC+5 when you're at UTC-4? That's a 9-hour difference. No need to look up time zone names or worry about whether it's "Eastern" or "Pacific" time.
The world's offsets range from UTC-12 (uninhabited Baker Island) all the way to UTC+14 (Line Islands, Kiribati) — a span of 26 hours.

Offsets vs. Named Time Zones
When to use each approach
Named time zones like "America/New_York" or "Europe/London" include rules about when clocks change for daylight saving. They're essential for software that needs to handle future dates correctly.
UTC offsets are simpler — they tell you the current difference from UTC right now. They're perfect for quick conversions, scheduling calls, or when you just need to know "what time is it there?"
Think of it this way: use named zones when programming or planning months ahead. Use offsets when you need a fast answer about the current time.
Fractional Offsets
Not every offset is a whole number
Most offsets are whole hours, but some places use 30-minute or even 45-minute differences. These unusual offsets often have historical or geographical reasons.
- UTC+5:30 — Used by India and Sri Lanka
- UTC+5:45 — Nepal's unique offset
- UTC+9:30 — Central Australia
- UTC-3:30 — Newfoundland, Canada
- UTC+12:45 — Chatham Islands, New Zealand
India's half-hour offset alone affects over 1.4 billion people — more than any single whole-hour offset except UTC+8.
When Offsets Change
Daylight saving shifts everything
Here's the catch with offsets: they can change twice a year in places that observe daylight saving time. A city might be UTC-5 in winter but UTC-4 in summer.
- US Eastern: UTC-5 (winter) / UTC-4 (summer)
- UK: UTC+0 (winter) / UTC+1 (summer)
- Australia Eastern: UTC+10 (winter) / UTC+11 (summer)
Many regions — including most of Asia, Africa, and South America — don't observe daylight saving, so their offset stays the same year-round.
The Edges of Time
Where the calendar bends
The International Date Line creates some fascinating situations. At UTC+14, Kiribati's Line Islands are the first place on Earth to see each new day. Meanwhile, at UTC-12, uninhabited Baker Island is the last.
This means there's a moment every day when three different calendar dates exist simultaneously on Earth. Early in the UTC day, it could be Monday in some places, Tuesday in others, and even Wednesday in Kiribati.
Kiribati deliberately moved to UTC+14 in 1995 so the entire country could share the same day. Before that, the Line Islands were 24 hours behind the rest of the nation.
Quick Offset Reference
UTC+8: World's Busiest
More people live in UTC+8 than any other offset. It covers China, Singapore, Malaysia, Taiwan, the Philippines, and parts of Australia and Indonesia.
UTC+0: The Reference
UTC+0 is where it all starts. Countries like the UK, Portugal, Iceland, and several West African nations use this offset as their standard time.
UTC+5:45: Nepal Only
Nepal chose a 45-minute offset to symbolically position itself between its giant neighbors India (UTC+5:30) and China (UTC+8). It's the world's only 45-minute offset.
UTC-10: Hawaii Time
Hawaii doesn't observe daylight saving, making UTC-10 (HST) one of the most consistent offsets. It's also used by the Cook Islands and French Polynesia.
UTC+14: First to Tomorrow
The Line Islands in Kiribati use the world's most advanced offset. They see each new day, including New Year's, before anywhere else on the planet.
UTC-3:30: Newfoundland
Canada's easternmost province uses a half-hour offset. When it's noon in New York, it's 1:30 PM in St. John's — not 1:00 or 2:00 like you might expect.
