Why Time Zones Are Confusing
The world has 24 standard time zones plus dozens of half-hour and quarter-hour offsets, Daylight Saving Time variations by country, and historical zone changes. Getting this wrong means missing meetings, late deliveries, and scheduling chaos.
How to Use the Time Zone Converter
1Open the Time Zone Converter.
2Select your source timezone from the full IANA list (e.g., America/New_York).
3Select your target timezone (e.g., Asia/Tokyo).
4Enter a date and time to convert, or use "now".
5See the converted time instantly. The world clock shows 12 major cities in real time.
💡 Use IANA Timezone Names: "America/New_York" is more reliable than "EST" because IANA names automatically handle Daylight Saving Time transitions.

FAQ
Does DST (Daylight Saving Time) affect conversions?
Yes — and we handle it automatically. When you specify a date, our tool uses that exact moment in time, correctly applying the DST offset that applies on that specific date for each timezone.
Which countries don't observe DST?
Most of Africa, Asia, and Australia's tropical regions don't observe DST. Japan, China, India, and most of Africa use fixed offsets year-round.
