Unix Timestamp Converter — Epoch to Date & Time

What is a Unix Timestamp?

A Unix timestamp (epoch time) is the number of seconds elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch). It's a universal, timezone-independent way to represent a moment in time used across databases, APIs, file systems, and logs.

Why Convert Timestamps?

Debugging logs, validating JWT expiry times (the `exp` claim is a Unix timestamp), reading database records with datetime columns stored as integers, or working with APIs that return epoch time — all require converting back to human-readable dates.

Key Benefits

• Convert epoch timestamp → UTC date and local time
• Convert date/time → Unix timestamp
• Supports seconds and milliseconds
• Shows both UTC and local timezone
• Current timestamp displayed in real time

How to Use Timestamp Converter

1. Enter a Unix timestamp (seconds or milliseconds)
2. See the human-readable date and time instantly
3. Or enter a date to get the Unix timestamp
4. Copy the result

Example Use Case

A JWT's `exp` field shows `1714492800`. Is the token still valid? Enter the value into Timestamp Converter → it shows April 30, 2024, 16:00:00 UTC. Compare with now — if past, the token is expired.

Tips

• JavaScript Date.now() returns milliseconds since epoch
• Most Unix tools use seconds
• MySQL UNIX_TIMESTAMP() returns seconds
• Year 2038 problem: 32-bit signed timestamps overflow on Jan 19, 2038
