What is the Timestamp Converter?

Written and maintained by the BitConvert team · Feb 27, 2026

The Timestamp Converter moves between Unix epoch time and human-readable dates in both directions. Unix time counts the seconds elapsed since midnight UTC on January 1, 1970, giving a compact, timezone-independent number that programs use to store and compare moments in time. Paste a timestamp to see the date it represents, or pick a date and time to get the corresponding epoch value.

The tool understands both common resolutions: 10-digit values measured in seconds, which most back-end systems and databases use, and 13-digit values in milliseconds, which JavaScript and many APIs produce. A live "Now" button captures the current instant, and results are shown as an easy-to-read local date and time alongside the raw number. This makes it simple to sanity-check log entries, API fields, or database columns without doing epoch arithmetic in your head.

Key Features

Two-Way Conversion

Turn an epoch number into a readable date, or convert a chosen date and time back into a Unix timestamp.

Seconds and Milliseconds

Handles both 10-digit second timestamps and 13-digit millisecond timestamps used by JavaScript and many APIs.

Current Time Capture

A one-click Now button fills in the present moment so you can grab the current epoch value instantly.

Readable Local Output

Displays the converted result as a clear local date and time next to the raw numeric timestamp.

Common Use Cases

Decode a created_at or expires field from an API response or JWT to learn the actual date and time. Read a Unix timestamp in a server log to pinpoint when an event happened. Generate an epoch value to hardcode in a test, a database seed, or a cron-related calculation. Check whether a token or cache entry has expired by converting its stored timestamp to a real date. Reconcile a millisecond value from JavaScript with a seconds-based field in your database.
