All conversions are performed locally in your browser. Unix timestamps are timezone-independent and represent a specific moment in UTC. The timestamp 0 = January 1, 1970 at 00:00:00 UTC.

Epoch & Unix Timestamp Converter

Convert Unix timestamps to human-readable dates and vice versa. A Unix timestamp (also known as Unix epoch, Unix time, or POSIX time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC (the Unix epoch). It's the universal time format used by computers, databases, and APIs worldwide.

Our converter handles seconds (10 digits), milliseconds (13 digits, used by JavaScript), and microseconds (16 digits) with automatic precision detection. Unlike cluttered competitors filled with ads, we offer a clean, fast, keyboard-first interface designed for developers who need quick conversions without friction.

Features include real-time conversion, multiple date format outputs (ISO 8601, RFC 2822, readable), timezone support with visual picker, relative time display ("2 hours ago"), quick presets (Now, Tomorrow 9am, End of month), and one-click copy for all values.

Key Capabilities

  • Smart auto-detection: Automatically detects if your input is seconds (10 digits), milliseconds (13 digits, like JavaScript Date.now()), or microseconds (16 digits). No manual selection needed.
  • Bidirectional conversion: Convert from Unix timestamp to date OR from human-readable date to timestamp. Both directions work instantly as you type.
  • Multiple output formats: See all common date formats simultaneously — ISO 8601, RFC 2822, human-readable, UTC, local time, and custom timezone format. No need to click between tabs.
  • Relative time display: Instantly see "2 hours ago", "in 3 days", or "5 months ago" — useful for understanding timestamps at a glance without mental math.
  • Quick presets: One-click shortcuts for common times — "Now", "Tomorrow 9am", "Start of day", "End of month", "Start of year". Perfect for testing edge cases.
  • Timezone support: Convert to any timezone with a dropdown picker showing popular zones (UTC, EST, PST, GMT, JST, IST, etc.). Understand DST behavior instantly.
  • One-click copy: Every value has a copy button. No need to manually select and copy text — just click and paste into your code.

Privacy & Security

All timestamp conversions happen entirely in your browser using JavaScript's built-in Date object. No data is sent to any server. No timestamps are logged. No cookies track your usage.

This means you can safely convert sensitive timestamps — like auth token expiry times, database records, or system logs — without any privacy concerns. When you close the tab, everything is gone from memory.

How to Use

  1. Choose your input mode: Timestamp (Unix epoch) or Date (human-readable).
  2. Type or paste your value. Timestamps auto-detect precision (seconds, milliseconds, microseconds).
  3. See instant conversions in all formats below — no "Convert" button needed.
  4. Click any copy icon to copy that specific value to your clipboard.
  5. Use Quick Presets to try common times like "Now", "Tomorrow 9am", "Start of month".
  6. Change Timezone to see the same moment in different locations (UTC, EST, PST, etc.).
