What is a Unix Timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's the universal standard for storing and comparing dates in programming. Databases store dates as timestamps for efficient sorting and comparison. APIs return timestamps in responses. Log files use timestamps for event ordering. This tool helps you convert between the numeric timestamp format and human-readable dates, which is a daily task for developers working with APIs and databases.

Benefits

• •Debug timestamp values in code and APIs
• •Convert API response timestamps to readable dates
• •Generate timestamps for database testing
• •Understand date/time storage in databases
• •Verify timestamp calculations in code
• •Convert between seconds and milliseconds formats

How to Use the Timestamp Tool

1. 1View the current Unix timestamp at the top (updates every second)
2. 2Click the copy button to copy the current timestamp
3. 3Switch to 'Timestamp → Date' tab to convert a timestamp
4. 4Paste any Unix timestamp (seconds or milliseconds)
5. 5See the human-readable date and time instantly
6. 6Switch to 'Date → Timestamp' tab to convert a date to timestamp

Unix Timestamp Quick Reference

Current timestamp: Math.floor(Date.now() / 1000) in JavaScript. Milliseconds: Date.now(). Add 1 day: timestamp + 86400. Add 1 hour: timestamp + 3600. Add 1 week: timestamp + 604800. The Year 2038 problem: 32-bit timestamps overflow on January 19, 2038. Modern systems use 64-bit timestamps. JavaScript's Date.now() returns milliseconds, while most Unix systems use seconds.
