Timestamp Converter
Convert between Unix timestamps and human-readable dates.
About Timestamp Converter
Unix timestamps are everywhere — API responses, server logs, database rows — but a number like 1700000000 means nothing to a human at a glance. This free Unix timestamp converter turns epoch time into a readable date and back again, instantly and in both directions. Type a timestamp to see the exact date, or pick a date to get its timestamp. There is no sign-up and nothing to install, and the conversion runs entirely in your browser — the values you enter never leave your device.
The converter goes beyond a single answer. For any timestamp or date you enter it shows a live relative time (“3 hours ago”, “in 2 days”), the ISO 8601 string, the day of the week, the time in your local timezone, the equivalent UTC time, and the value in both epoch seconds and milliseconds — each with a one-click copy button. A Now button drops in the current Unix time whenever you need it, making this a fast epoch converter for developers debugging logs, testing APIs, or scheduling anything that speaks Unix time.
How to convert a Unix timestamp to a date
- 1Type or paste an epoch value into the Unix Timestamp (seconds) field — for example 1700000000. The date picker below updates immediately.
- 2To convert the other way, pick a date and time in the Date & Time (Local) field instead — the timestamp field fills in automatically, since the two inputs stay in sync.
- 3Click Now to load the current time into both fields with one tap.
- 4Read the results: the live relative time, plus ISO 8601, day of week, your local time, UTC, and the timestamp in both seconds and milliseconds.
- 5Click the copy icon next to any value to copy it to your clipboard.
Frequently asked questions
What is a Unix timestamp?
It is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 — the Unix epoch. Because it is a single timezone-independent number, it is the standard way computers store and exchange points in time.
Does the converter accept milliseconds or only seconds?
The input field expects epoch seconds — the usual 10-digit value. If you have a 13-digit millisecond timestamp from JavaScript or Java, drop the last three digits (divide by 1000) before pasting. The results panel always shows both the seconds and milliseconds forms so you can copy whichever your code needs.
Which timezone does the conversion use?
The date picker and the Local row use your browser’s own timezone, which is detected automatically and shown by name. The results also include the UTC time and an ISO 8601 string, so you can compare your local reading against the universal one side by side.
Can I convert future dates and timestamps?
Yes. Enter any future date or timestamp and the relative display switches to phrasing like “in 3 weeks”, updating every second. This is handy for checking token expiries, scheduled jobs, or countdowns.
Is anything I enter sent to a server?
No. The entire conversion runs locally in your browser with JavaScript — timestamps and dates you type are never uploaded, logged, or stored anywhere.
Is this timestamp converter free?
Yes — completely free, with no sign-up, no ads gating the result, and no usage limits.
