About the Timestamp Converter

Convert between Unix timestamps and human-readable dates instantly. This free online tool supports multiple date formats, timezones, and provides a live view of the current timestamp. Perfect for developers, system administrators, and anyone working with time-based data.

What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is a system for tracking time as a running total of seconds since the Unix Epoch — January 1st, 1970 at 00:00:00 UTC. It's widely used in computer systems and programming because it provides a simple, unambiguous way to represent a specific moment in time regardless of timezone or locale.

Supported Formats

• Unix Timestamp — Seconds or milliseconds since January 1, 1970
• ISO 8601 — International standard format (2024-03-12T10:30:00Z)
• RFC 2822 — Email and HTTP header format (Tue, 12 Mar 2024 10:30:00 +0000)
• MySQL DateTime — Database format (2024-03-12 10:30:00)
• US Format — Month/Day/Year (03/12/2024)
• European Format — Day/Month/Year (12/03/2024)

Features

• Live Clock — See current timestamp updating in real-time
• Bidirectional Conversion — Convert Unix to date and date to Unix
• Timezone Support — Convert between different timezones
• Date Parser — Parse various date string formats automatically
• Date Difference — Calculate time between two dates
• Working Days — Count business days between dates

Common Use Cases

• Debugging API responses containing timestamps
• Converting database timestamps for display
• Calculating time differences for scheduling
• Working with log files and system timestamps
• Setting expiration times for tokens or caches

Seconds vs Milliseconds

Unix timestamps can be expressed in seconds (10 digits) or milliseconds (13 digits). JavaScript's Date.now() returns milliseconds, while many server-side languages use seconds. This tool automatically detects which format you're using based on the number of digits.

The Y2K38 Problem

32-bit systems store Unix timestamps as signed integers with a maximum value of 2,147,483,647 — which represents January 19, 2038 at 03:14:07 UTC. After this point, the timestamp will overflow and wrap around to negative values. Modern 64-bit systems don't have this limitation and can handle dates far into the future.
