Frequently Asked Questions
How does the timezone converter work?
The converter takes your chosen date and time, interprets it in the selected source timezone, then converts that exact UTC moment to local time in all 50+ listed cities. Conversion uses the browser's built-in Intl.DateTimeFormat API, which respects daylight saving time (DST) automatically.
Does it account for daylight saving time?
Yes. Daylight saving time is handled automatically by the Intl API. The UTC offset shown next to each city reflects the actual offset on the selected date — so UTC+1 in winter and UTC+2 in summer for Central European Time, for example.
What is UTC?
UTC (Coordinated Universal Time) is the world's primary time standard. All other timezones are defined as an offset from UTC. UTC does not observe daylight saving time, making it a stable reference for international scheduling.
Why might a meeting scheduled at "9 AM EST" be confusing?
Timezone abbreviations like EST can be ambiguous — EST means UTC−5 in North America, but different abbreviations overlap across the world. It is always safer to specify a full timezone name (e.g., "America/New_York") or state the UTC offset explicitly.
