How to Convert a Unix Timestamp to a Date
Convert Unix timestamps (epoch time) to human-readable dates and vice versa. Supports seconds and milliseconds.. This step-by-step guide walks you through the process using LevnTools Unix Timestamp Converter, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.
Enter the Unix timestamp
Paste the Unix timestamp value (e.g., 1700000000) into the input field. The tool auto-detects whether it is in seconds (10 digits) or milliseconds (13 digits).
View the converted date
The tool instantly converts the timestamp to a human-readable date and time, shown in both your local timezone and UTC. The full date includes year, month, day, hours, minutes, and seconds.
Convert date to timestamp
To go the other direction, use the date picker to select a date and time. The tool shows the corresponding Unix timestamp in both seconds and milliseconds.
Pro Tips
- Unix timestamps count seconds since January 1, 1970 00:00:00 UTC (the Unix epoch).
- JavaScript Date.now() returns milliseconds (13 digits), while many APIs use seconds (10 digits).
- Timestamps are timezone-independent — the same timestamp represents the same moment everywhere.
Common Issues & Fixes
Issue: The converted date is way off, showing a year far in the past or future.
Fix: You may have the wrong unit. A 13-digit number is milliseconds; a 10-digit number is seconds. Make sure the tool is using the correct unit.
Issue: The time shown does not match what I expected.
Fix: Check whether you are comparing UTC time vs. local time. The tool shows both — make sure you are looking at the correct timezone.
