Timestamp Converter

A Unix timestamp converter transforms between Unix epoch time and human-readable dates. Unix timestamps (also called epoch time) represent the number of seconds since January 1, 1970 UTC—a standard way computers track time across different systems and time zones.

The Problem: Confusing Timestamp Formats

When working with APIs, databases, and automation workflows, you constantly encounter different date formats. Some systems use Unix timestamps in seconds, others in milliseconds. Converting between these formats manually is tedious and error-prone, especially when debugging time-sensitive workflows.

• APIs return timestamps in various formats (Unix, ISO 8601, RFC 2822)
• Some systems use seconds, others use milliseconds
• Time zone differences cause confusion
• Manual conversion requires complex calculations

The Solution: Free Online Timestamp Converter

This free epoch converter instantly converts between Unix timestamps and human-readable dates. It automatically detects whether your input is in seconds or milliseconds, and provides multiple output formats for easy copying into your code or workflows.

Understanding Unix Timestamps

Unix time (also known as POSIX time or epoch time) counts seconds from the Unix Epoch: January 1, 1970, 00:00:00 UTC. For example:

• 0 = January 1, 1970 00:00:00 UTC
• 1000000000 = September 9, 2001 01:46:40 UTC
• 1702300800 = December 11, 2023 12:00:00 UTC

Modern systems often use millisecond timestamps (13 digits) for higher precision. This tool automatically handles both formats.

Output Formats Supported

• Unix (seconds) - Standard 10-digit timestamp
• Unix (milliseconds) - 13-digit precision timestamp
• ISO 8601 - International standard format (2024-12-11T10:30:00.000Z)
• UTC - Human-readable UTC format
• Local Time - Converted to your local time zone

Perfect for n8n Date Handling

When building n8n automation workflows, you frequently need to work with dates from APIs, schedule triggers, and database records. This timestamp converter helps you:

• Convert API timestamps to readable dates for debugging
• Generate timestamps for date comparisons in workflows
• Format dates for Cron trigger expressions
• Debug time-based workflow conditions
• Convert between formats for different API requirements
