UNIX to Human Time Calculator

world's simplest time tool

With this browser-based application, you can convert UNIX time to human-readable calendar date plus clock time. You can enter several UNIX timestamps as the input and get Universal Coordinated Times (UTC) in the output. You can also choose the date/time format, add or remove zero padding, and switch between 12-hour and 24-hour clock formats. Created by computer nerds from team Browserling.

What Is a UNIX to Human Time Calculator?

This is a quick online utility for converting a UNIX timestamp to a regular calendar date and time. UNIX time (also known as Epoch time and Posix time) is a number equal to the seconds that have elapsed from the midnight of January 1, 1970 to the present moment. A UNIX timestamp is a continuously increasing integer that increases by 1 every second (and by 60 every minute, by 3600 every hour, and by 86400 every day). It represents fixed time – a specific date and time that doesn't change. For example, the UNIX timestamp 1652805000 corresponds to the date "2022-05-17 16:30:00 (UTC)". Note that the output date and time is always formatted as UTC (Universal Coordinated Time), which is used by people in their daily lives. You can enter multiple timestamps into the input field, one value per line, and get UTC time for each timestamp. In the options, you can choose which format to display the date and time, whether to use padding in it, and print the time part in a 12-hr or 24-hr clock format. You can also make custom output date and time formats using a format string that uses "YYYY", "YY", "MMMM", "MMM", "MM", "DD", "hh", "mm", and "ss" abbreviations. If you want to perform the reverse operation and calculate the UNIX time for a calendar date, you can use our Human Time to UNIX Time Converter tool. Timeabulous!

UNIX Time of a Space Event

In this example, we convert the Unix time of an important space exploration event into human time. The timestamp 1554854400 equals the date 2019-04-10 00:00:00 (in GMT/UTC timezone), which is the moment of the first direct photo of a black hole and its shadow.

Interesting UNIX Timestamps

In this example, we enter several neat UNIX Epoch times and convert them to UTC time. The first two timestamps are negative, which means that they correspond to dates less than January 1, 1970 (negative timestamps count down from this date). The next date is 0 and this is the start of the UNIX Epoch. The next seven dates are various pretty timestamps that convert to 20th and 21st century dates. We display all the converted dates in a textual format with shortened names of weekdays and months, and with a 12-hour clock time.

-100 -1 0 1000 1000000 1000000000 1111111111 1234567890 2000000000 2222222222

19 January 2038 Problem

In this example, we load the timestamp 2147483647 in the input, which corresponds to the date 03:14:07, Tuesday, January 19, 2038. This date is called the "Year 2038 problem" or "Epochalypse" and it's the last date that can be represented in a signed 32-bit integer format. We create a custom format for this date that includes all date and time components and we turn off date padding.

Fibonacci Epoch Time

Oh boy. In this example, Fibonacci, the famous mathematician of Pisa, discovered our utility and instantly decided to find UNIX dates that correspond to his numbers. It turns out that the first 47 Fibonacci numbers when converted to UNIX timestamps already exceed the current year. The 47th Fibonacci number equals the year 2028.

In this example, we decided to show you what happens if we convert all powers of 10 to Unix time. All powers up to 107 are still in the 1970s but then the growth explodes and the power 1012 already is in the futuristic year 33,658.

Powers of Two

This example generates human time from Unix timestamps that are powers of two in the form 2n. At first, the time changes very slowly as the first powers are 1, 2, 4, 8, … and these are just the seconds in the year 1970. Only at power 231 it gets to current century and at power 232 it reaches the near future.
