How does the world clock converter handle Daylight Saving Time (DST)?

The tool integrates the official IANA time zone database, which tracks historical and active Daylight Saving Time rules worldwide. Because countries change clocks on different dates (or not at all), the converter automatically adjusts offsets based on the specific calendar date selected.

What is the difference between UTC and GMT?

Greenwich Mean Time (GMT) is an astronomical time zone anchored at the Prime Meridian in London. Coordinated Universal Time (UTC) is the high-precision atomic time standard used globally. For practical scheduling purposes, UTC and GMT share the exact same reference time (zero offset).

What happens when a time conversion crosses the International Date Line?

When a time zone shift moves past midnight, the calculator displays a clear '+1 Day' or '-1 Day' tag next to the converted time, preventing critical scheduling errors on cross-pacific communications.

Why do some countries have non-hourly time zone offsets?

While most time zones are separated by full one-hour increments, several countries use half-hour or 45-minute offsets to align solar noon with geographic borders. Notable examples include India (UTC+5:30), Iran (UTC+3:30), and Nepal (UTC+5:45). Our converter handles all fractional offsets accurately.
