What is the Date to Unix Timestamp Converter?
Converting human-readable dates to Unix timestamps is essential for storing dates in databases, sending time values in APIs, and scheduling events in code. The Unix epoch (January 1, 1970 00:00:00 UTC) serves as the universal reference point. This converter parses multiple date formats using JavaScript's Date constructor, calculates the elapsed seconds since epoch, and presents both seconds and milliseconds formats commonly used across different systems and programming languages.
How to use the Date to Unix Timestamp Converter?
- Enter a date using the date/time picker or type a date string (e.g. '2025-06-13 10:30:00').
- The Unix timestamp (seconds since epoch) is calculated instantly.
- Both seconds and milliseconds formats are displayed for easy copying.
- Click 'Now' to use the current date/time as the starting point.
- Supports ISO 8601, RFC 2822, and common date string formats.
Frequently Asked Questions
What date formats are accepted?
This converter accepts ISO 8601 (2025-06-13T10:30:00Z), RFC 2822 (Fri, 13 Jun 2025 10:30:00 +0000), and common formats like '2025-06-13 10:30:00' or 'June 13, 2025'. The JavaScript Date parser handles most standard formats.
Which timezone is used?
Dates without explicit timezone info are interpreted in your local timezone. Add 'Z' or '+00:00' suffix for UTC. The output always shows the Unix timestamp in UTC (since timestamps are timezone-independent).
What's the difference between seconds and milliseconds timestamps?
Unix traditionally uses seconds (10 digits). JavaScript Date.now() uses milliseconds (13 digits). APIs vary — check documentation for which format is expected.
Is this converter safe?
Yes. Date parsing uses the browser's native Date constructor. No data is transmitted anywhere.
