With this browser-based application, you can convert any calendar date and time to UNIX Epoch time. The program accepts a date in YYYY-MM-DD hh:mm:ss format and produces a single universal timestamp that can be used to store and easily compare dates. You can enter multiple human-readable dates as the input and you'll immediately get UNIX timestamps for each one of them in the output. Created by computer nerds from team Browserling.

This is a quick online utility for converting human-readable time to UNIX timestamps. UNIX time (also known as UNIX Epoch time or Posix time) is a time measurement system that describes date and time in the form of a continuous count of elapsed seconds since the beginning of the UNIX Epoch. This moment is defined to be at 00:00:00 on January 1, 1970 (Thursday). At this moment, UNIX time is zero and it's the beginning of the UNIX Epoch. From this point on, UNIX time grows daily, second by second. For example, on "2022-05-20 12:00:00" it's "1653048000" and on "2100-01-01 00:00:00" it will be "4102444800". For calendar dates less than January 1, 1970, the UNIX timestamp is negative. For example, for the date "1965-10-05 00:00:00", the UNIX time is "-133833600". The method of storing time as a single integer number (as a seconds counter) is very convenient to use when comparing dates. Time stored as a UNIX timestamp is accurate up to a second and the comparison is a simple numerical test of two integers. It's also convenient for storing dates of various events as integers take less computer memory (usually just 4 bytes) than full dates (which can take up to 20 bytes). Our algorithm lets you calculate timestamps for any date after the UNIX Epoch (including dates after January 19, 2038), as well as any date before the UNIX Epoch (dates before January 1, 1970). When doing time conversion, you can enter several calendar dates in the input field in the "YYYY-MM-DD hh:mm:ss" format and separate them using a line break (enter) for each new date. If you want to do the reverse operation, use our UNIX Time to Human Time Converter program. Timeabulous!

In this example, we calculate the UNIX launch time of the International Space Station (ISS). It's the first multinational space station and it was launched on November 20, 1998. We paste this calendar date into the input text area and get the UNIX timestamp 911520000 as the output.
In this example, we find UNIX timestamps for four versions of Windows. The first date, Oct 22, 2009, is the release date of Windows 7; the second date, Oct 26, 2012, is the release date of Windows 8; the third date, Jul 29, 2015, is the release date of Windows 10; and the fourth date Oct 05, 2021, is the release date of Windows 11. Since we do not specify the clock time part of the date, it's considered to be 00:00:00.
In this example, we show how our tool works in both the positive and negative time directions. The UNIX Epoch starts on January 1, 1970, and we enter this date in the input as the middle date. Then, we add dates with differences of ±1 second, ±1 minute, ±1 hour, ±1 day, ±1 month, and ±1 year in both directions. In the output, we get a beautiful symmetrical hour glass-shaped list of UNIX timestamps.
This example shows how the UNIX time changes over decades in the 21st century. The timestamp for January 1st of 2000 is 946684800 and every 10 years, the UNIX time increases by 315619200 or 315532800 (depending on the number of leap years in the decade).
In this example, we convert various neat calendar dates to UNIX dates to see if the UNIX dates also are neat. Unfortunately, there's no correlation between neat calendar dates and neat UNIX dates so the output UNIX dates are just numbers with no special properties.
This example finds calendar dates of UNIX times that are in the billionaires club. This exclusive club contains all those UNIX times that have multiples of one billion seconds. The first club member is the calendar date "2001-09-09 01:46:40", which equals exactly one billion seconds, the second member is "2033-05-18 03:33:20", which equals two billion seconds, etc.
