📋 How to Use

How to Use Unix Timestamp Converter

Timestamp to Human Date:

  1. Enter a Unix timestamp in the top input field (e.g., 1700000000).
  2. Click Now to auto-fill with the current timestamp.
  3. Click Convert to see the UTC date, RFC 2822 format, and relative time (e.g., '3 months ago').

Human Date to Timestamp:

  1. Enter a date string in the lower input field.
  2. Supported formats: 2024-01-15 14:30:00, 2024-01-15, January 15, 2024, 2024-01-15T14:30:00Z
  3. Click Convert to get the Unix timestamp.

What is a Unix Timestamp?

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the 'Unix epoch'). It does not account for leap seconds.

Millisecond Timestamps

Many modern systems (JavaScript's Date.now(), Java, Kotlin) return timestamps in milliseconds (13 digits) rather than seconds (10 digits). The tool automatically detects and converts millisecond timestamps.

❓ Frequently Asked Questions

The Unix epoch is the reference point for Unix timestamps: January 1, 1970, 00:00:00 UTC. A Unix timestamp of 0 represents exactly this moment. Timestamps increase by 1 for each second that passes. The current Unix timestamp can always be found by entering 'now' in many programming languages.
JavaScript's Date.now() returns the number of milliseconds since the Unix epoch, not seconds. This gives 13 digits for current dates, compared to the 10-digit second-precision timestamps. To convert to seconds, divide by 1000: Math.floor(Date.now() / 1000). This tool automatically handles both formats.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. Unlike local time zones, UTC does not change for daylight saving time. Using UTC for timestamps ensures that a given timestamp always refers to the same absolute moment in time, regardless of where the system is located.
On 32-bit systems, the maximum Unix timestamp is 2,147,483,647, which corresponds to January 19, 2038 at 03:14:07 UTC — this is the Year 2038 Problem. On 64-bit systems (most modern computers), the maximum timestamp is 9,223,372,036,854,775,807 seconds, which corresponds to approximately the year 292 billion.
