What Is This Tool?
Our timestamp converter converts Unix timestamps (seconds or milliseconds since January 1, 1970 UTC) to human-readable date and time strings, and back. It also shows the current Unix timestamp in real time. This is an indispensable tool for developers working with APIs, databases, and log files that use epoch time.
How to Use
- Enter a Unix timestamp in the input field to convert it to a readable date.
- Or enter a date and time to convert it to a Unix timestamp.
- Select whether your timestamp is in seconds or milliseconds.
- The converted result appears instantly.
Common Use Cases
- Converting Unix timestamps from API responses to readable dates for debugging
- Generating a timestamp for a specific past or future date for database queries
- Reading log file timestamps that use epoch format
- Comparing timestamps across different time zones
Tips & Tricks
- JavaScript timestamps are in milliseconds; most Unix timestamps in databases are in seconds.
- Use the 'now' button to capture the current timestamp instantly.
- Unix timestamps always represent UTC time — convert to local time separately if needed.
Frequently Asked Questions
How do I tell if a timestamp is in seconds or milliseconds?
A 10-digit number is typically seconds (e.g., 1735689600), while a 13-digit number is milliseconds (e.g., 1735689600000). Select the correct unit in the tool before converting to get an accurate date.
What exact moment does a Unix timestamp of 0 represent?
Timestamp 0 is the Unix epoch: January 1, 1970, 00:00:00 UTC. All Unix timestamps count seconds (or milliseconds) elapsed since that moment.
Does the converted date show my local time zone or UTC?
Unix timestamps themselves are timezone-agnostic; the human-readable date shown reflects your browser's local timezone unless you specify otherwise, so double-check when working across regions.
How do I get the current timestamp right now?
Click the 'now' button to instantly capture and display the current Unix timestamp in both seconds and milliseconds.
Is the date or timestamp I enter sent to a server?
No. All conversion happens locally using your browser's Date object — nothing is transmitted anywhere.
Convert Unix timestamps to human-readable dates and vice versa. Support for seconds and milliseconds. Perfect for developers and debugging.
