Convert between Unix timestamps (epoch time) and human-readable dates instantly. Perfect for working with APIs, databases, and server logs.
A Unix timestamp (also known as epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent dates and times in programming, commonly used in APIs, databases, and server logs. This tool helps developers convert between Unix timestamps and human-readable date formats across multiple timezones.
Unix timestamps are typically measured in seconds (10 digits), but some systems like JavaScript use milliseconds (13 digits). This tool automatically detects which format you're using.
Math.floor(Date.now() / 1000)import time; int(time.time())time()System.currentTimeMillis() / 1000When you receive a Unix timestamp from an API (e.g., 1704412800), use this tool to see what date and time it represents in a human-readable format.
Use the time difference calculator to find out exactly how many days, hours, and minutes remain until a specific timestamp (deadline, product launch, etc.).
When you need to send a specific date/time in an API request, use the date picker to convert your desired date into a Unix timestamp that APIs expect.
Server logs often include timestamps in Unix format. Paste the timestamp here to quickly understand when an event occurred in your local timezone.
A Unix timestamp is an absolute count of seconds since 1970-01-01 00:00:00 UTC. The value itself carries no timezone; a timezone is applied only when you format the timestamp for display, which is why the same number renders as different wall clock times around the world.
Systems that store Unix time in a signed 32-bit integer overflow at 03:14:07 UTC on 19 January 2038, wrapping to a negative number and misreading the date. Storing the counter in 64 bits removes the ceiling and avoids the overflow.
The Unix epoch is 1970-01-01 00:00:00 UTC, the zero point from which Unix time is counted. A timestamp is the number of seconds elapsed since that moment.
Count the digits. A 10-digit value is seconds; a 13-digit value is milliseconds. JavaScript's Date.now() returns milliseconds, while most Unix APIs use seconds.

Yes. A Unix timestamp is an absolute count of seconds since the epoch in UTC; a timezone is applied only when you format it for display.
Don't just calculate time, monitor your systems. ObserveOne checks your API health and uptime from multiple global locations.
Side-by-side breakdowns, no fluff.
