Frequently Asked Questions
How do I convert a date string to epoch?
Enter any date string like '2025-04-02T12:00:00Z', 'April 2, 2025 12:00 PM', or '2025-04-02' and click Convert. The tool returns both seconds and milliseconds epoch values.
What date formats are supported?
The converter accepts ISO 8601 (2025-04-02T12:00:00Z), RFC 2822 (Wed, 02 Apr 2025 12:00:00 GMT), and most natural date strings that JavaScript's Date constructor can parse.
Does the converter handle timezones?
Yes. If your input includes a timezone offset (like +05:30 or Z for UTC), it is respected. If no timezone is specified, the date is interpreted in your browser's local timezone.
How accurate is the conversion?
The conversion is accurate to the millisecond. The tool uses the browser's built-in Date API, which follows the ECMAScript specification for date parsing and is reliable for dates between years 1970 and 9999.
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.
