Convert Unix epoch timestamps to human-readable dates and back. Supports seconds and milliseconds.
Developers debugging logs, databases, and API responses with epoch times.
Convert a timestamp
Paste a Unix timestamp (seconds or milliseconds) to see the matching date in local, UTC, and ISO formats.
Convert a date
Pick a date and time to get its Unix timestamp in seconds.
Copy the result
Click any value to copy it. A live clock shows the current Unix time for reference.
Computers love Unix time — the number of seconds since 1 January 1970 — because it is a single, timezone-free integer that is easy to store and compare. Humans cannot read it at all: "1718539620" tells you nothing at a glance. Logs, databases, JWTs, and API responses are full of these epoch numbers, and when you are debugging you constantly need to know what date one represents, or to produce the timestamp for a specific moment. This converter goes both ways. Paste a Unix timestamp to see the date in your local time, UTC, and ISO 8601 formats; or pick a date and time to get its epoch value. It auto-detects whether your number is in seconds or milliseconds, shows a live clock of the current Unix time, and copies any value with a click. Everything runs in your browser, so nothing is sent anywhere — handy when the timestamps come from private logs.
Debugging logs
Turn epoch timestamps in server and application logs into readable dates.
API development
Generate timestamps for requests, or verify exp/iat values returned in responses and tokens.
Database work
Convert stored Unix times into human-readable dates for inspection and reporting.
Scheduling & cron
Confirm exactly when an epoch-based job or expiry will fire.
Cross-timezone checks
See a moment in both your local time and UTC to avoid off-by-hours mistakes.
No. The tool auto-detects: values longer than about 11 digits are treated as milliseconds, otherwise as seconds.
The number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (the "epoch"), a standard, timezone-independent way to represent a moment.
Your local timezone plus UTC and ISO 8601, so you can use whichever your task needs.
Usually a timezone mix-up — compare the UTC value, and check whether the source stores local or UTC time.
A standard date-time format like 2024-06-16T12:00:00Z that is unambiguous and widely used in APIs and config.
No. Everything runs in your browser; nothing is uploaded.
Yes — those are represented as negative Unix timestamps and convert correctly.
Yes — convert as many timestamps as you like for free, with no account required.
