Unix Timestamp Converter

What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is a way of tracking time by counting the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970 (the Unix epoch). It's widely used in programming, databases, APIs, and logs for time tracking.

Epoch to Date Conversion

Converting an epoch timestamp to a date translates those seconds into a human-readable format like:

Input Epoch: 1721139600
→ Output Date: 2024-07-17 12:00:00 UTC

This helps developers debug logs, analyze API responses, and track events in real-world time.

Date to Epoch Conversion

Conversely, if you input a date and time (like 2025-12-31 23:59:59), the converter will return the corresponding Unix timestamp.

Input Date: 2025-12-31 23:59:59
→ Output Epoch: 1767225599

This is useful when scheduling events, storing time in databases, or interacting with APIs that expect timestamps.

Features of This Tool

Common Use Cases

• Debugging API responses with timestamps
• Scheduling CRON jobs or future events
• Converting log data into readable dates
• Preparing time-based analytics

What is the Difference Between Seconds and Milliseconds?

Unix timestamps are typically in **seconds**, but some systems (like JavaScript) use **milliseconds**. For example:

Epoch in Seconds:    1721139600
Epoch in Milliseconds: 1721139600000

This tool automatically detects and adjusts both formats.
