What is Unix Timestamp Converter?

A Unix timestamp converter is a tool that converts between Unix time (also called epoch time) and human-readable date formats such as ISO 8601, local date strings, and timezone-adjusted time values. Unix timestamps represent the number of seconds (or milliseconds) since January 1, 1970 at 00:00:00 UTC, and are widely used in programming, APIs, databases, system logs, and distributed systems because they provide a consistent and timezone-independent way to represent time. This online Unix timestamp converter helps you instantly decode timestamps into readable dates, convert dates back into timestamps, and view results across different timezones. It is essential for debugging logs, verifying event timing, inspecting API payloads, and preventing timezone-related bugs.

How to Use

1

Paste a Unix timestamp (seconds or milliseconds) into the input field

2

Or paste a date/time value such as an ISO 8601 string or natural language date

3

Click Convert to generate the converted output instantly

4

View the readable date in UTC and optionally in your local timezone

5

Copy the output timestamp or formatted date for use in your application, logs, or API payload

Common Use Cases

Debug Server Logs: Convert timestamps from logs into readable time to track incidents and errors

API Testing: Convert timestamp fields in API requests and responses to verify correct event timing

Database Queries: Convert stored Unix timestamps into human-readable date values for debugging or reporting

Timezone Troubleshooting: Compare UTC timestamps with local timezone values to prevent scheduling bugs

Job Scheduling: Convert human dates into Unix timestamps for cron jobs and scheduled tasks

Front-End Development: Convert timestamps from backend services into readable UI dates
