Timestamp To Date Converter

Timestamp Online is timestamp converver between unix timestamp and human readable form date. If you want to convert timestamp, it is sufficient to either enter your timestamp into input area, or you can construct URL with your timestamp — http://timestamp.online/timestamp/ .

Timestamp Online also supports countdown, so you can see, how much time remains to particular timestamp. URLs for countdowns have following form — http://timestamp.online/countdown/ .

Current Timestamp Examples

These examples are showing how to get current unix timestamp in seconds. These examples are returning timestamp in seconds, although some of the languages are returning timestamp in milliseconds.

long ts = System.currentTimeMillis()/1000;

Current Date and Time Examples

These examples are showing how to get current date and time that could be presented to the end-user.

import datetime; datetime.datetime.now().isoformat()

Timestamp to Date Examples

These examples are showing how to convert timestamp — either in milliseconds or seconds to human readable form.

new Date(1688807387000).toLocaleString();

import datetime datetime.datetime.fromtimestamp(1688807387).isoformat()

import Java.Util.Date; import java.text.SimpleDateFormat; Date currentDate = new Date (1688807387000) SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss") String date = dateFormat.format(currentDate);

date +"%Y-%m-%d %H:%M:%S" -d @1688807387

Parse Date to Timestamp Examples

These examples are showing how to parse date in human readable form to unix timestamp in either milliseconds or seconds.

Date.parse("2023-07-08 11:09:47")/1000;

import time int(time.mktime(time.strptime("2023-07-08 11:09:47"))) - time.timezone

import java.text.SimpleDateFormat; SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss") long ts = dateFormat.parse(2023-07-08 11:09:47).getTime()/1000;

Unix Time

Unix time (also known as POSIX time or Epoch time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds. It is used widely in Unix-like and many other operating systems and file formats. Because it does not handle leap seconds, it is neither a linear representation of time nor a true representation of UTC.

What is epoch time?

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but ‘epoch’ is often used as a synonym for Unix time. Some systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038). The converter on this page converts timestamps in seconds (10-digit), milliseconds (13-digit) and microseconds (16-digit) to readable dates.

Human-readable time	Seconds
1 hour	3600 seconds
1 day	86400 seconds
1 week	604800 seconds
1 month (30.44 days)	2629743 seconds
1 year (365.24 days)	31556926 seconds

Thanks to everyone who sent me corrections and updates!
