About Time Zone Conversions
Accurate time zone conversion is essential in our interconnected world, where business meetings, flight schedules, and personal calls routinely span multiple time zones. Every location on Earth is assigned a UTC offset — the number of hours and minutes ahead of or behind Coordinated Universal Time — but these offsets are not fixed throughout the year. Daylight Saving Time (DST) shifts clocks forward by one hour in spring and back in autumn in many regions, though the exact transition dates vary by country and sometimes by state or province. The IANA Time Zone Database, maintained by the Internet Assigned Numbers Authority and used by virtually every operating system and programming language, catalogs these rules for over 400 named zones. When converting between two cities, both the source and destination DST rules must be evaluated for the specific date in question, because the offset between a pair of cities can differ by one or even two hours depending on the time of year. For remote teams, international travelers, and global businesses, relying on mental arithmetic or static offset tables leads to missed meetings and scheduling errors. Our converter applies the full IANA rule set automatically, handling edge cases like half-hour offsets (India at UTC+5:30), quarter-hour offsets (Nepal at UTC+5:45), and regions that have abolished or never adopted DST. The result is a reliable, always-current conversion you can trust for any city pair on any date.
