Timezone conversion trips people up because the offset is not always a whole hour (India is UTC+5:30, Nepal is UTC+5:45, Iran is UTC+3:30), and daylight saving time shifts the offset for half the year in many countries. The US alone has six time zones; Australia observes DST in the southern hemisphere summer, which is opposite to Europe and North America.
The converter handles IANA timezone names so DST is applied automatically. Pick any two cities or regions, enter your time, and see the equivalent time on the other end. Common conversions: IST to EST (New York) is -10.5 hours; IST to GMT is -5.5 hours; IST to SGT (Singapore) is +2.5 hours.
Frequently Asked Questions
Why does the US have so many time zones?
The contiguous US spans four zones: Eastern, Central, Mountain, and Pacific. Add Alaska and Hawaii and it is six. Some states like Arizona (most of it) do not observe DST, adding further complexity.
What is UTC and how is it different from GMT?
UTC (Coordinated Universal Time) is the primary time standard. GMT (Greenwich Mean Time) used to be the standard and is still often used interchangeably with UTC in casual contexts. For practical purposes they are the same - UTC+0.
Why do some countries use half-hour or 45-minute UTC offsets?
Timezone boundaries are defined by countries, not geography. India chose UTC+5:30 to keep the whole country in one zone despite spanning nearly two standard zones. Nepal chose UTC+5:45 to differentiate itself from India. It is a political and practical choice.
