Frequently Asked Questions
How does the timezone converter handle Daylight Saving Time?
The converter uses the browser's Intl.DateTimeFormat API backed by the IANA timezone database. DST transitions are handled automatically by the operating system's ICU data, giving you correct results year-round.
How many timezones are supported?
All IANA timezone database entries are supported, covering over 400 timezones worldwide. This includes standard zones like America/New_York, Europe/London, and Asia/Tokyo.
Can I convert a specific date and time, not just the current time?
Yes. Enter any date and time in the input field (e.g., '2025-04-02 14:30' or just '14:30' for today) to convert it between the selected timezones.
What is the IANA timezone database?
The IANA timezone database (also called tz or zoneinfo) is the definitive source for timezone rules including DST changes. It is maintained by a community of volunteers and used by virtually all operating systems and programming languages.
How It Works
This tool runs entirely in your browser using vanilla JavaScript. No data is sent to any server. All conversions and calculations happen locally on your device, ensuring complete privacy.
EpochPilot uses the browser's built-in Intl.DateTimeFormat API and the IANA timezone database provided by your operating system. This means timezone conversions are always accurate, including Daylight Saving Time transitions.
