A Unix timestamp (also called an epoch timestamp) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC — the “Unix epoch.” It's how almost every server, database, and API stores and compares dates internally, because it's timezone-agnostic and perfectly sortable. Our free online Unix timestamp converter lets you convert any epoch value to a human-readable date (UTC, your local timezone, and ISO 8601) and convert any date/time back to a Unix timestamp. The current live timestamp is shown at the top, updating every second — useful for copying the current timestamp into log entries, database records, or API calls.

How to Use the Timestamp Converter
- Timestamp → Date: Type or paste a Unix timestamp (e.g., 1718600000) into the first input and click Convert. The UTC time, your local time, and ISO 8601 format are shown.
- Date → Timestamp: Use the date-time picker in the second section to select a date and time, then click Convert to get the corresponding Unix timestamp.
- Current timestamp: The live counter at the top shows the current epoch second. Click the copy icon to grab it.
Common Timestamp Facts
- The Unix epoch starts at 1970-01-01 00:00:00 UTC (timestamp = 0).
- JavaScript's
Date.now()returns milliseconds — divide by 1,000 to get seconds. - The Year 2038 problem: 32-bit systems store timestamps as signed integers, which overflow on January 19, 2038. Most modern 64-bit systems are not affected.
- Negative timestamps represent dates before January 1, 1970.
Frequently Asked Questions
What is the current Unix timestamp?
It's shown live at the top of the tool above, updating every second. At the time this page was published, it was in the 1.7 billion range.
Why do some timestamps have 13 digits instead of 10?
A 10-digit timestamp is in seconds (standard Unix time). A 13-digit timestamp is in milliseconds (used by JavaScript, Java, and some databases). To convert milliseconds to seconds, divide by 1,000.
