Timezone Converter
Convert a date and time between UTC and common world timezones.
Coordinating across timezones is a daily challenge for remote teams, international scheduling, and travel planning. This converter shows the exact time difference between any two timezones worldwide, accounting for daylight saving time shifts and half-hour offsets like India and Nepal.

How to Convert Between Timezones
- Enter the time — type the time you want to convert.
- Select the source timezone — the timezone you are converting from.
- Select the target timezone — the timezone you want to convert to.
- View the result — the tool shows the equivalent time and the offset difference.
Frequently Asked Questions
What is UTC? ▼
UTC (Coordinated Universal Time) is the world's primary time standard. All timezones are defined as offsets from UTC: London is UTC+0, New York is UTC-5, Tokyo is UTC+9. UTC does not observe daylight saving time and serves as the global reference point.
How does daylight saving time affect conversions? ▼
Daylight saving time (DST) shifts clocks forward by one hour in spring and back in autumn. This changes the UTC offset temporarily — for example, New York shifts from UTC-5 (EST) to UTC-4 (EDT). Not all countries observe DST, so time differences between locations can change seasonally.
How many timezones are there? ▼
There are 24 standard UTC offsets, but over 37 actual timezones in practice due to half-hour and 45-minute offsets. India is UTC+5:30, Nepal is UTC+5:45, and the Chatham Islands use UTC+12:45. Including DST variations, over 100 timezone identifiers exist.
What is the International Date Line? ▼
The International Date Line runs roughly along the 180° meridian in the Pacific Ocean. Crossing it eastward moves back one calendar day; crossing westward advances one day. Some island nations are offset from this line, creating timezone quirks (like Samoa and Tonga being 25 hours apart despite being neighbours).
How do I schedule meetings across timezones? ▼
Find overlapping work hours between the two locations. For US East (UTC-5) and UK (UTC+0), the overlap is roughly 14:00–17:00 UTC (9–12 AM EST, 2–5 PM GMT). Use a timezone converter to check specific dates, as DST shifts can change the overlap window.
