Frequently Asked Questions

What is UTC?

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All time zones are defined as offsets from UTC (e.g., EST = UTC-5, IST = UTC+5:30). UTC does not observe daylight saving time.

How do I handle Daylight Saving Time in conversions?

DST shifts clocks forward by 1 hour in spring and back in fall. Not all countries observe DST, and those that do change on different dates. Our converter uses current DST rules automatically, but verify for future dates when DST boundaries matter.

Is this calculator free to use?

Yes. All calculators on zenicalculator.com are completely free with no registration required.
