Unix Time Converter
Epoch seconds and ISO/UTC date conversions for developers.
Unix to human date
Paste a Unix timestamp (seconds) to see UTC, local time, and ISO formats.
UTC
Mon, 03 Nov 2025 17:05:13 GMT
Local time
Mon Nov 03 2025 22:35:13 GMT+0530 (India Standard Time)
ISO 8601
2025-11-03T17:05:13Z
Date to Unix
Pick a UTC date and time to generate the Unix epoch in seconds.
Unix timestamp
1762189500
Debug timestamps without opening a REPL
Paste a Unix timestamp to see its UTC, local, and ISO representations, or reverse the flow by generating epoch seconds from any UTC date and time.
Great for
- Inspecting log timestamps from distributed systems.
- Prepping cron job schedules or CI/CD release windows.
- Converting between API payloads and human-readable audit trails.
Accuracy notes
We work exclusively with UTC under the hood. Local time is shown for context, and ISO 8601 strings make it easy to copy results into scripts or documentation.
Sample conversions
- 1700000000 → Sun, 14 Nov 2023 06:13:20 GMT - 2023-11-14T06:13:20Z
- 2024-01-01 00:00 UTC → 1704067200

FAQ
Will you add milliseconds and nanoseconds? Millisecond precision is planned; nanoseconds require BigInt math and will come later.
Can I convert local time instead? Enter the UTC offset manually before conversion, or use the Time Zone Converter to prep the UTC values first.
