Example input
1704067200Example output
2024-01-01T00:00:00.000Z (ISO 8601)Practical workflow
- Paste the epoch value into Timestamp to Date and select Seconds or Milliseconds.
- Choose ISO 8601 for an exact UTC instant, UTC text for a readable UTC date, or Local time for your browser time zone.
- Copy the result, or choose Use result as input to switch to Date to Timestamp.
Common use cases
- Inspect Redis, MongoDB, or SQL epoch timestamp columns.
- Debug event timelines in distributed tracing and telemetry systems.
- Translate microservice payload timestamps into readable dates.
Important notes and limitations
- Epoch time starts at 1970-01-01T00:00:00Z.
- Negative epoch values correspond to dates before January 1, 1970.
- For negative or near-epoch millisecond values, select Milliseconds explicitly instead of relying on automatic detection.

Frequently asked questions
How do I convert a date back to an epoch timestamp?
Select Date to Timestamp and enter an ISO date string, preferably with an explicit time-zone offset. The two result cards show Unix seconds and Unix milliseconds.
Does Epoch conversion require an internet connection?
No. The calculation is executed 100% locally in your web browser using JavaScript date math.
Can I convert dates before 1970?
Yes. Negative epoch values represent earlier dates. Select the unit explicitly so a small millisecond value is not interpreted as seconds.
