Convert Unix timestamps to readable dates and times, or convert any date to a Unix epoch timestamp. Live current timestamp, timezone support, and milliseconds.
See the current Unix timestamp updating live at the top.
To convert a timestamp: paste any Unix timestamp (seconds or milliseconds) in the input field.
To convert a date: switch to Date → Timestamp mode and pick a date and time.
Select your timezone to see local time equivalents.
Copy the converted value.
A Unix timestamp is the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC (the Unix epoch). It is the standard way computers represent time.
A 10-digit number is in seconds (standard Unix). A 13-digit number is in milliseconds (used by JavaScript Date.now() and most browser APIs).
In 2038, 32-bit signed integers storing Unix timestamps will overflow. 64-bit systems are not affected. This is the timestamp equivalent of the Y2K bug.
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC — an arbitrary but universally agreed-upon reference point known as "the Unix epoch."
As of right now, the Unix timestamp is a 10-digit number (e.g., 1710000000). In about 2286 AD, it will become an 11-digit number. In 2038, 32-bit systems storing this as a signed integer will overflow — a problem known as the Y2K38 bug.
Timestamps are the backbone of how computers store and transmit time because they are:
One persistent confusion in timestamp work is whether a value is in seconds or milliseconds:
| Format | Example | Used By |
|---|---|---|
| Seconds | 1710000000 (10 digits) | Unix/POSIX standard, most server logs |
| Milliseconds | 1710000000000 (13 digits) | JavaScript Date.now(), Java, most browser APIs |
| Microseconds | 1710000000000000 (16 digits) | Python's time.time(), some databases |
Our converter auto-detects which format you're using based on the number of digits and converts accordingly.
Get the current timestamp: The converter shows the current Unix timestamp live, updating every second. Useful for quickly grabbing a "now" value for testing or logging.
Date to timestamp: Enter a specific date and time (with timezone) and get the exact Unix timestamp. Essential for setting expiry times, scheduling events, and writing test data.
Timestamp to date: Paste any timestamp and see the full ISO 8601 date-time string, your local time, and UTC time simultaneously.
Relative time: See how far in the past or future a timestamp is from right now — "3 hours 42 minutes ago", "in 2 days, 14 hours".
Timestamps themselves are always UTC. The display timezone only affects how you read the human-formatted output — not the underlying numbers. Always convert to UTC before storing, and only apply local timezone formatting at the presentation layer.
Debugging log timestamps: Server logs often include Unix timestamps. Paste one to instantly know when an error occurred...
