epoch converter - unix timestamp
This epoch converter solves timestamp to date and date to timestamp conversion problems. The unix time converter supports real-time seconds and milliseconds with multi-timezone UTC display, making unix timestamp conversions accurate. Use this epoch time converter to convert epoch values and plan global scheduling with confidence.
Supports seconds (10-digit) or milliseconds (13-digit) unix timestamp

📌 About epoch converter and unix timestamp
An epoch converter is a practical tool that transforms a unix timestamp into a readable date and time, or performs the reverse operation. The unix timestamp itself is the number of seconds or milliseconds that have elapsed since 00:00:00 UTC on January 1, 1970. This epoch converter focuses on bidirectional workflows, so you can move from timestamp to date and date to timestamp in one interface without switching tools. It also shows the current unix timestamp in real time, updating every second, and supports both seconds and milliseconds precision. The unix time converter features are designed for developers, testers, and anyone working with system logs, APIs, or scheduled tasks. Because the tool uses the UTC standard internally and formats local time according to your selected timezone, it is reliable for cross-region collaboration. The layout keeps the current timestamp, the conversion tabs, and the result copy buttons all within easy reach.
- Supports seconds (10-digit) and milliseconds (13-digit) unix timestamp input, so you can handle both common epoch formats.
- Converts timestamp to date and date to timestamp in one interface, with no need to leave the page or use a separate calculator.
- Displays current unix timestamp with real-time seconds and milliseconds, updating automatically every second.
- Includes unix time converter features for UTC and local time output, so you always see both reference times.
- One-click copy for every conversion result, including epoch to utc and unix timestamp to date outputs.
- Works as a reliable epoch converter online, giving immediate results for timestamp to date and date to timestamp tasks.
⚙️ How epoch converter handles timestamp to date and date to timestamp
Milliseconds Timestamp = Seconds Timestamp × 1000 — used by the epoch time converter for 13-digit millisecond values.
Seconds Timestamp = Milliseconds Timestamp ÷ 1000 — used by the unix time converter for 10-digit second values.
Local Time = UTC Time + Timezone Offset — used by the epoch converter for timestamp to date and date to timestamp.
- Seconds Unix Timestamp: 10-digit number, unit in seconds, e.g., 1735689600. The unix timestamp converter accepts this directly for timestamp to date conversion, and it is the format most commonly used in Linux system logs.
- Milliseconds Unix Timestamp: 13-digit number, unit in milliseconds, e.g., 1735689600000. The epoch time converter also handles milliseconds to date conversions, which are common in JavaScript and browser-based APIs.
- UTC Time: Coordinated Universal Time, the world time standard. The epoch converter can convert epoch to utc instantly, and the UTC result is displayed alongside local time for every timestamp to date conversion.
- Timezone: The world is divided into 24 time zones, China uses UTC+8. The date to timestamp workflow respects the selected timezone before calculating the unix timestamp, so the result reflects the intended local time.
📝 How to use unix time converter for timestamp to date and date to timestamp
- timestamp to date: Enter a 10-digit or 13-digit unix timestamp, select the corresponding unit, and click "Convert to Date/Time". The epoch converter shows local time and UTC time together, so you can read both references at once.
- date to timestamp: Select date/time, choose timezone and output unit, then click "Convert to Unix Timestamp". This returns the epoch time converter result in seconds or milliseconds depending on your output selection.
- Copy Results: All conversion results support copy functionality, including current unix timestamp values and unix time now values. Each result row has a dedicated copy button for quick transfer.
- View current unix timestamp: The top of the page displays current unix timestamp seconds and milliseconds in real time. This is useful when you need an immediate epoch value for a script or request.
❓ epoch converter - unix timestamp FAQ
- Q: Why are the epoch converter results different from what I expected?
A: Please check if the timezone setting and timestamp unit are correct. The unix timestamp to date conversion uses the selected unit; if the unit is wrong, the date result shifts by a large margin. For date to timestamp conversion, also verify that your local datetime is entered for the intended timezone. - Q: What's the difference between a 10-digit and 13-digit unix timestamp?
A: A 10-digit value represents seconds, while a 13-digit value represents milliseconds. The epoch time converter supports both for timestamp to date and date to timestamp, and the unit selector lets you switch between seconds and milliseconds. - Q: How does epoch to utc work in this tool?
A: The converter applies the UTC timezone when formatting the result, so epoch to utc is always available alongside local time. The UTC result is computed from the same numeric epoch value and is not affected by your selected timezone. - Q: Can I convert milliseconds to date with this unix time converter?
A: Yes, select the milliseconds unit and enter a 13-digit unix timestamp; the milliseconds to date result appears instantly. The tool recognizes whether your input is seconds or milliseconds and suggests the matching unit automatically.
