Unix Epoch

Unix Timestamp Converter (Epoch to Date & Date to Epoch)

Convert between Unix Epoch timestamps (in both seconds and milliseconds) and human-readable calendar dates instantly. Whether you are debugging API responses, analyzing server logs, or scheduling database records, get instantaneous multi-timezone conversions.

Features a real-time live Unix clock, bidirectional timestamp-to-date and date-to-timestamp converters, ISO 8601 and RFC 2822 formatting, relative human time descriptions ("X minutes ago"), and one-click clipboard copying.

How It Works (Step-by-Step)

1. Enter Timestamp or Date

Type or paste a numeric Unix timestamp (e.g. 1735689600) or select a calendar date and time from the date-picker.

2. Automatic Unit Detection

The converter automatically distinguishes between Unix seconds (10 digits) and Unix milliseconds (13 digits) to prevent conversion errors.

3. Copy Formatted Outputs

View the instant breakdown in UTC, your local timezone, ISO 8601, and relative time format, and click copy next to any format.

Key Features & Advantages

Bidirectional Real-Time Conversion

Converts seamlessly from Unix timestamp to formatted date, and from calendar date to Epoch seconds/milliseconds.

Smart Seconds vs Milliseconds Detection

Eliminates unit ambiguity by automatically detecting 10-digit second timestamps and 13-digit millisecond timestamps.

Live Real-Time Unix Clock

Monitors the current epoch time with a running live ticker and pause/resume capability.

Comprehensive Date Standards

Outputs in UTC (GMT), Local Browser Time, ISO 8601 (2026-01-01T00:00:00Z), RFC 2822, and relative time strings.

Frequently Asked Questions

What is a Unix Timestamp (Epoch Time)?

A Unix timestamp is the total number of seconds (or milliseconds) that have elapsed since the Unix Epoch: January 1, 1970 at 00:00:00 UTC, excluding leap seconds. It is the universal standard for representing time across servers, databases, and APIs.

What is the difference between Unix seconds and milliseconds?

Standard Unix timestamps in systems like Linux, Python, and PHP count seconds (typically 10 digits, e.g., 1735689600). In JavaScript (Date.now()) and Java, timestamps are represented in milliseconds (typically 13 digits, e.g., 1735689600000). This converter handles both formats automatically.

What will happen during the Year 2038 problem (Y2K38)?

On January 19, 2038, 32-bit signed integers representing Unix timestamps will overflow. Modern 64-bit systems and this browser converter support timestamps far beyond 2038 with zero overflow risk.
