Unix Time Calculator — Timestamp to Date Converter
Enter any Unix timestamp — the number of seconds elapsed since midnight 1 January 1970 (UTC), also called the Unix epoch — and instantly see the corresponding UTC date and time, plus the elapsed days, weeks, and years.

Seconds to days
1.735.689.600 ÷ 86.400 = 20.089 - 2
Days to weeks
20.089 ÷ 7 = 2.869,86 - 3
Days to years
20.089 ÷ 365.25 = 55,0007Gregorian average: 365.25 days per year.
Cum funcționează acest calculator?
A Unix timestamp counts the whole seconds elapsed since 1 January 1970 00:00:00 UTC. Divide by 86 400 to get days, by 3 600 for hours, multiply by 1 000 for milliseconds. Enter the timestamp above to decode it to a UTC calendar date instantly.

How this is calculated
The Unix timestamp is simply a count of whole seconds (or milliseconds in some systems) that have elapsed since the Unix epoch: 00:00:00 UTC on 1 January 1970. It is the lingua franca of date storage in databases, APIs, log files, and operating systems because it is timezone-free and arithmetic-friendly.
To convert to a calendar date, divide the timestamp by 86 400 (seconds in a day) to get days since epoch, then apply the Gregorian calendar algorithm. The UTC time components are obtained by decomposing the remaining seconds within the day into hours, minutes, and seconds.
This calculator accepts timestamps from roughly 1678 CE to 2262 CE (the range representable as 64-bit nanoseconds, safe for most platforms). To convert a date back to a Unix timestamp, subtract the epoch and count the seconds — most programming environments expose this as `Date.now()` (milliseconds) or the C `time()` call (seconds).

The Unix epoch is 00:00:00 Coordinated Universal Time (UTC) on Thursday, 1 January 1970. It was chosen arbitrarily when Unix was designed in the early 1970s and has since become the universal reference point for timestamps in computing.
Many languages — JavaScript, Java, Python datetime.timestamp() × 1000 — work in milliseconds rather than seconds. Divide your value by 1 000 to get the standard Unix second-precision timestamp, then enter it here.
Older 32-bit systems store the Unix timestamp as a signed 32-bit integer, which overflows on 19 January 2038 at 03:14:07 UTC. Modern 64-bit systems are unaffected — they can represent timestamps billions of years into the future.
