Unix Timestamp Converter
Convert a Unix timestamp to a readable date, or a date to a Unix timestamp — plus a live clock showing the current timestamp.
Timestamp → Date
Date → Timestamp
How to use the timestamp converter
- To convert a timestamp to a date: enter the number, choose whether it's in seconds or milliseconds, and click Convert.
- To convert a date to a timestamp: pick a date and time in the right-hand panel and click Convert — results show both seconds and milliseconds.
- The live clock at the top always shows the current Unix timestamp in seconds, ticking up every second.
- Use the Copy buttons to grab any result for use in code, logs, or API calls.
Why use a Unix timestamp converter?
Unix time — the number of seconds since January 1, 1970 UTC — shows up everywhere in logs, databases, JWTs, and APIs, but it's not something humans can read at a glance. This tool converts instantly in both directions and shows results in UTC alongside your browser's local time, so you don't have to do timezone math by hand. It also handles the common seconds-vs-milliseconds mix-up that trips up a lot of debugging sessions: pick the right unit and the tool does the rest. Everything is computed client-side with JavaScript's native Date object, so there's no server delay and no data leaves your browser.
What is a Unix timestamp?
A Unix timestamp is the number of seconds (sometimes milliseconds) that have elapsed since midnight UTC on January 1, 1970 — the Unix epoch. It's a compact, timezone-independent way to store a point in time.
How do I know if my timestamp is in seconds or milliseconds?
Seconds-based timestamps for recent dates are 10 digits long; millisecond timestamps are 13 digits. Use the unit selector to switch between them before converting.
Does this tool account for my timezone?
Yes. Results show both the UTC time and your browser's local time, and the Date-to-Timestamp converter reads the date and time you enter as your local timezone.
