What is a Unix timestamp?
A Unix timestamp (epoch time) is the number of seconds that have passed since 00:00:00 UTC on 1 January 1970. Servers, databases and log files love them because they're tiny, timezone-free numbers — but humans can't read 1760659200 at a glance. Converting it to a readable date is a daily debugging task.
Timestamp to readable date for logs, online
Application logs are full of epoch numbers. Instead of doing mental math (or writing a one-off script), paste the number into the Timestamp Converter — you instantly get the date and time in both UTC and your local timezone, which is exactly what you need when correlating log lines with real-world events.
Seconds vs milliseconds: the classic trap
Timestamps come in two flavours, and mixing them up is the #1 bug:
- 10 digits (e.g.
1760659200) = seconds — the classic Unix timestamp. - 13 digits (e.g.
1760659200000) = milliseconds — what JavaScript'sDate.now()produces.
Paste a 13-digit value where seconds are expected and you'll land in the year 57753. The converter detects seconds versus milliseconds automatically, so you don't have to count digits.
How to convert a Unix timestamp to a date online
- Open the Timestamp Converter.
- Paste the timestamp (seconds or milliseconds — auto-detected).
- Read the date in UTC and local time instantly.
- Need the reverse? Enter a date to get the timestamp back — it works both directions.
Frequently asked questions
How do I convert a Unix timestamp to a readable date online?
Paste the timestamp into a free Unix timestamp converter. It instantly shows the date and time in UTC and your local timezone — no signup needed.
How do I read timestamps in server logs?
Copy the epoch number from the log line and paste it into the timestamp converter. The UTC reading lets you match it against events; the local-time reading matches your wall clock.
What's the difference between 10-digit and 13-digit timestamps?
10 digits = seconds since 1970 (classic Unix time). 13 digits = milliseconds (used by JavaScript's Date.now()). The converter auto-detects which one you pasted.
Can I convert a date back into a timestamp?
Yes — the tool works both directions. Enter a date and time to get the Unix timestamp in seconds (and milliseconds).
What timezone is the converted date shown in?
Both: every conversion shows UTC and your browser's local time side by side, so there's no ambiguity.
