Timestamp Converter

What the Timestamp Converter does

The Timestamp Converter converts a Unix timestamp (seconds since January 1, 1970) into a human-readable date, or a human-readable date into its Unix timestamp equivalent — the format most APIs, databases, and log files use internally to store dates.

How to use it

1. To convert a timestamp to a date, enter the Unix timestamp in seconds and click Convert to Date.
2. To convert a date to a timestamp, pick a date and time and click Convert to Timestamp.
3. Use Use current timestamp to instantly grab right now's Unix time.

Common uses

• Debugging an API response or database record that stores dates as Unix timestamps.
• Converting a log file timestamp into a readable date for a support ticket or bug report.
• Checking the exact timestamp value to use in an API request or test payload.
• Verifying that a cron job or scheduled task timestamp is set for the intended time.
• Cross-checking a timestamp displayed by one system against another's expected format.

Good to know

Unix timestamps are technically timezone-agnostic — they represent an exact moment in universal time — but the human-readable date shown will reflect your browser's local timezone unless otherwise specified, which is worth double-checking if you're coordinating across timezones. Some systems use milliseconds instead of seconds for their timestamps (a 13-digit number instead of 10); if your converted date looks wildly wrong, check whether you need to divide by 1000 first.

Unix time counts seconds elapsed since midnight UTC on January 1, 1970 — an arbitrary but now deeply entrenched reference point chosen by early Unix developers — and it remains the standard internal date representation across most databases, APIs, and programming languages because a single integer is far simpler to store, compare, and sort than a formatted date string. The well-known "Year 2038 problem," where 32-bit systems storing this value will overflow, is a real (if increasingly rare) edge case in older infrastructure still using 32-bit timestamp storage.
