Why Do You Need a Timestamp Converter?

Unix timestamps are the universal standard for storing dates in programming — the number of seconds since January 1, 1970 UTC. But a number like 1704067200 is unreadable to humans. Developers constantly need to convert timestamps from database queries and API responses to readable dates for debugging, convert datetime values to timestamps for database queries, understand relative time ('how long ago was this?'), and handle timezone differences. This tool makes all these conversions instant.

Benefits

  • Quickly convert timestamps from APIs and databases
  • Multiple output formats for every use case
  • Convenient copy-paste into code or documentation
  • Understand relative time easily
  • Debug API and database timestamp issues
  • No installation needed — works in any browser

How to Use Timestamp Converter

  1. 1Enter a Unix timestamp (seconds) in the first field, OR
  2. 2Select a date and time from the datetime picker
  3. 3Click the refresh button to get the current timestamp
  4. 4View all 8 output formats below automatically
  5. 5Click the Copy button next to the format you need
  6. 6Paste into your code, query, or documentation

Common Timestamp Operations in Code

Get current timestamp: Math.floor(Date.now() / 1000) in JavaScript, time.time() in Python, time() in PHP. Add 1 day: timestamp + 86400. Add 1 hour: timestamp + 3600. Add 1 week: timestamp + 604800. Convert to Date in JS: new Date(timestamp * 1000). Convert to datetime in Python: datetime.fromtimestamp(timestamp). The Year 2038 problem: 32-bit timestamps overflow on January 19, 2038 — modern systems use 64-bit.

Frequently Asked Questions

Is the timestamp in seconds or milliseconds?

The tool accepts input in seconds (10 digits like 1704067200). Output includes both seconds and milliseconds. JavaScript Date.now() returns milliseconds, while most backends (PHP, Python, Unix) use seconds. Divide by 1000 to convert ms → s.

What is Unix Epoch?

Unix Epoch is the moment 00:00:00 UTC on January 1, 1970. All Unix timestamps count the number of seconds from this point. Negative timestamps represent times before 1970.

How is relative time calculated?

Relative time compares the timestamp to the current moment and displays it as 'X minutes/hours/days ago'. Useful for quickly understanding how recent a timestamp is.

Why does my timestamp show a different date in different timezones?

Unix timestamps are always UTC-based. The 'Local' format converts to your browser's timezone. ISO 8601 and UTC formats always show the same value regardless of timezone.

What is the maximum timestamp value?

The maximum Unix timestamp for 32-bit systems is 2,147,483,647 (January 19, 2038) — known as the Year 2038 problem. This tool uses JavaScript's 64-bit numbers, so it supports dates far beyond 2038.
