Frequently Asked Questions
What is UTC?
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is the successor to Greenwich Mean Time (GMT). UTC does not observe Daylight Saving Time and serves as the "zero" point from which all other offsets are calculated.
How does Daylight Saving Time (DST) affect this?
Daylight Saving Time shifts local time forward by one hour during warmer months. This calculator uses standard UTC offsets. Because DST start and end dates vary by country and year, you should always add or subtract one hour manually if your specific region is currently observing DST.
How do I calculate offsets manually?
To convert from Time A to Time B: Subtract Time A's offset from its time to get UTC, then add Time B's offset. For example, if it's 10:00 AM in New York (-5) and you want London (0): 10 - (-5) = 15:00 UTC. 15 + 0 = 3:00 PM in London.
Why is India's offset +5.5?
While most countries use offsets in whole hour increments, some use half-hour or even quarter-hour offsets to better align with the solar time at their longitudes. India (+5:30), Pakistan (+5:00), and parts of Australia (+9:30) are common examples of non-integer offsets.
