Timestamp Converter

Timestamp Converter translates bi-directionally between Unix timestamp and readable date using your browser's local time and timezone.

What is a Unix Timestamp?

A Unix Timestamp (also known as Epoch Time or POSIX Time) is a system for tracking time represented as the total number of seconds (or milliseconds) that have elapsed since the Unix Epoch on January 1, 1970, at 00:00:00 UTC (Coordinated Universal Time). In software engineering, database administration, and API design, storing dates as a flat integer is the most reliable, timezone-independent method. However, for humans, understanding a number like 1782297600 is impossible. Our Timestamp Converter bridges this gap, translating these numbers into formatted calendar dates in milliseconds.

Key Features

• Bi-Directional Conversion:
  • Timestamp to Date: Input any Unix integer to view its calendar date representation in both UTC and your browser's local timezone.
  • Date to Timestamp: Select a calendar year, month, day, hour, and minute to calculate its corresponding Unix epoch integer.
• Live Stream Clock: View the current Unix timestamp ticking live in real-time, helping you grab the exact timestamp of "now."
• Seconds & Milliseconds Support: The converter automatically detects whether your input is in seconds (10 digits, standard Unix format) or milliseconds (13 digits, commonly used in JavaScript and Java).
• Timezone Aware: Displays results in your local local timezone alongside UTC, making it easy to troubleshoot server logs.
• 100% Client-Side: Calculations are computed locally using native JavaScript Date objects, guaranteeing complete privacy for your logs.

How to Use the Timestamp Converter?

To Convert a Unix Timestamp to Date:

1. Paste the 10-digit or 13-digit Unix timestamp into the input field.
2. The tool instantly displays the resolved calendar date.
3. Check the Local Time, UTC Time, and day of the week.

To Convert a Date to a Unix Timestamp:

1. Enter the calendar date parameters (Year, Month, Day, Hour, Minute, Second).
2. The converter will output the corresponding Unix timestamp in both seconds and milliseconds.
3. Click "Copy" to save the integer to your clipboard.

Frequently Asked Questions (FAQ)

What is the "Unix Epoch"?

The Unix Epoch is January 1, 1970, at 00:00:00 UTC. The timestamp integer value at this exact moment is exactly 0.

How can I distinguish between seconds and milliseconds?

A 10-digit integer represents seconds (e.g., used by PHP, Python, and C++). A 13-digit integer represents milliseconds (e.g., used by JavaScript, Java, and Node.js).
