About Unix Timestamps
Unix timestamps represent the number of seconds that have elapsed since January 1, 1970 (UTC), also known as the Unix Epoch. They are widely used in programming and databases for storing date and time information.

About Unix Timestamp Converter
Convert Unix timestamps (epoch time) to human-readable dates and vice versa with our comprehensive Unix timestamp converter. Unix time represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (the Unix epoch). This time format is fundamental to computer systems, programming, databases, APIs, and server logs. Our converter handles both seconds and milliseconds timestamps, supports multiple date formats, accounts for time zones, and allows conversions in both directions. Essential for developers debugging timestamp issues, database administrators working with date fields, system administrators analyzing logs, API developers testing endpoints, and anyone encountering Unix timestamps in technical work. The tool shows current Unix time, allows custom timestamp conversion, and displays dates in various readable formats to help you understand and work with epoch time effectively.
Key Features
Bidirectional Conversion
Convert Unix timestamps to readable dates AND convert dates to Unix timestamps. Seamlessly work in both directions for any conversion need.
Seconds and Milliseconds Support
Handle both Unix timestamps in seconds (10 digits) and milliseconds (13 digits). Automatically detects which format you're using for accurate conversion.
Current Timestamp Display
See the current Unix timestamp updating in real-time. Useful for testing, debugging, and understanding how Unix time increments.
Time Zone Aware
Convert timestamps to dates in any time zone. See the same moment in time represented correctly across different world regions.
Multiple Date Formats
Display converted dates in various formats: ISO 8601, RFC 2822, locale-specific formats, and custom formats. Choose the format that matches your requirements.
Relative Time Display
See how long ago or how far in the future a timestamp is. Shows human-friendly relative time like '2 hours ago' or 'in 3 days'.
Batch Conversion
Convert multiple timestamps at once. Perfect for processing log files, analyzing database records, or working with timestamp lists.

Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or Unix epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch). For example, 1672531200 represents January 1, 2023, at midnight UTC. It's called 'Unix' because it originated with Unix operating systems.
What's the difference between seconds and milliseconds timestamps?
Unix timestamps are traditionally in seconds (10 digits, like 1672531200). JavaScript and some systems use milliseconds (13 digits, like 1672531200000). Milliseconds timestamps are 1000 times larger than seconds timestamps. Our converter handles both automatically by detecting the number of digits.
Why do computers use Unix timestamps?
Unix timestamps make date calculations simple. To find the time difference between two dates, just subtract timestamps. They're also compact, storing a complete date-time in a single integer. This makes them efficient for databases and programming. They're timezone-independent, representing absolute moments in time.
What is the Unix epoch and why January 1, 1970?
The Unix epoch is midnight UTC on January 1, 1970. This date was chosen when Unix was being developed at Bell Labs in the early 1970s as a convenient, recent reference point. All Unix timestamps count forward (or backward for earlier dates) from this moment.
Can Unix timestamps represent dates before 1970?
Yes! Dates before January 1, 1970, are represented as negative Unix timestamps. For example, January 1, 1960, would be -315619200. However, some systems have trouble with negative timestamps, so check your platform's capabilities.
What is the Year 2038 problem?
On 32-bit systems, Unix timestamps are stored as signed 32-bit integers, which can only represent dates up to January 19, 2038, at 03:14:07 UTC. After this, timestamps will overflow and wrap to negative values, potentially causing system failures. Modern 64-bit systems don't have this limitation.
Do Unix timestamps account for time zones?
Unix timestamps are timezone-independent - they always represent a specific moment in UTC. When converting to human-readable dates, you must specify a time zone. The same timestamp shows different hours in different time zones, but represents the exact same moment.
How do I handle daylight saving time with Unix timestamps?
Unix timestamps don't care about DST - they represent absolute moments in time. When converting to local time, our converter handles DST automatically. A timestamp represents the same global moment whether DST is active or not; only the local time representation changes.
Use Cases
- Software Development and Debugging: Debug date-related issues in applications by converting timestamps from logs and error messages. Verify that timestamps are being generated and stored correctly in your code.
- Database Query Building: Construct database queries that filter by date ranges. Convert human-readable dates to Unix timestamps for WHERE clauses in SQL queries that use epoch time storage.
- API Testing and Development: Test API endpoints that use Unix timestamps for date parameters. Verify API responses containing timestamps, and construct requests with correctly formatted epoch times.
- Server Log Analysis: Analyze server logs, access logs, and system logs that use Unix timestamps. Correlate events by converting timestamps to readable dates for troubleshooting and monitoring.
- Data Migration and ETL: Convert dates during data migration between systems using different date formats. Transform legacy data with Unix timestamps into modern database formats or vice versa.
