More info OK. Learn more. import datetime datetime. fromtimestamp Depending on your time zone, the result above will vary between March 24 and March When setting a date, without specifying the time zone, JavaScript will use the browser's time zone.

When getting a date, without specifying the time zone, the result is converted to the browser's time zone.

Some browsers will try to guess the format. Some will return NaN. The behavior of "DD-MM-YYYY" is also undefined. If you have a valid date string, you can use the Date. parse method to convert it to milliseconds. parse returns the number of milliseconds between the date and January 1, We just launched W3Schools videos.

Help to translate the content of this tutorial to your language! To create a new Date object call new Date with one of the following arguments:. An integer number representing the number of milliseconds that has passed since the beginning of is called a timestamp. We can always create a date from a timestamp using new Date timestamp and convert the existing Date object to a timestamp using the date.

getTime method see below. The algorithm is the same as Date. Create the date with the given components in the local time zone. Only the first two arguments are obligatory. Many JavaScript engines implement a non-standard method getYear. This method is deprecated. It returns 2-digit year sometimes. Please never use it. There is getFullYear for the year. Just insert the "UTC" right after "get". Every one of them except setTime has a UTC-variant, for instance: setUTCHours.

As we can see, some methods can set multiple components at once, for example setHours. The components that are not mentioned are not modified. The autocorrection is a very handy feature of Date objects. We can set out-of-range values, and it will auto-adjust itself. Just add 2 days. The Date object will do the rest:. That feature is often used to get the date after the given period of time. When a Date object is converted to number, it becomes the timestamp same as date.

getTime :. It is semantically equivalent to new Date. It is used mostly for convenience or when performance matters, like in games in JavaScript or other specialized applications.

These two do exactly the same thing, but one of them uses an explicit date. getTime to get the date in ms, and the other one relies on a date-to-number transform. Their result is always the same. The first idea may be to run them many times in a row and measure the time difference.

For our case, functions are very simple, so we have to do it at least times. Using getTime is so much faster! Imagine that at the time of running bench diffSubtract CPU was doing something in parallel, and it was taking resources. And by the time of running bench diffGetTime that work has finished. As a result, the first benchmark will have less CPU resources than the second. That may lead to wrong results.

For more reliable benchmarking, the whole pack of benchmarks should be rerun multiple times. So, in the example above, first executions are not well-optimized. We may want to add a heat-up run:. Modern JavaScript engines perform many optimizations. So if you seriously want to understand performance, then please study how the JavaScript engine works. The method Date. parse str can read a date from a string.

Shorter variants are also possible, like YYYY-MM-DD or YYYY-MM or even YYYY. The call to Date. If the format is invalid, returns NaN. Note that unlike many other systems, timestamps in JavaScript are in milliseconds, not in seconds. Sometimes we need more precise time measurements. JavaScript itself does not have a way to measure time in microseconds 1 millionth of a second , but most environments provide it.

For instance, browser has performance. now that gives the number of milliseconds from the start of page loading with microsecond precision 3 digits after the point :. js has microtime module and other ways. The new Date constructor uses the local time zone. So the only important thing to remember is that months start from zero. Open a sandbox with tests. Open the solution with tests in a sandbox.

European countries have days of week starting with Monday number 1 , then Tuesday number 2 and till Sunday number 7. Create a function getDateAgo date, days to return the day of month days ago from the date. For instance, if today is 20th, then getDateAgo new Date , 1 should be 19th and getDateAgo new Date , 2 should be 18th. Write a function getLastDayOfMonth year, month that returns the last day of month.

Normally, dates start from 1, but technically we can pass any number, the date will autoadjust itself. Write a function getSecondsToday that returns the number of seconds from the beginning of today. The difference is the number of milliseconds from the beginning of the day, that we should divide by to get seconds:. Create a function getSecondsToTomorrow that returns the number of seconds till tomorrow. Please note that many countries have Daylight Savings Time DST , so there may be days with 23 or 25 hours.

We may want to treat such days separately. EN AR عربي EN English ES Español FA فارسی FR Français ID Indonesia IT Italiano JA 日本語 KO 한국어 RU Русский TR Türkçe UK Українська ZH 简体中文.

Creation To create a new Date object call new Date with one of the following arguments: new Date Without arguments — create a Date object for the current date and time:. Not getYear , but getFullYear.

getUTCHours ;. getTimezoneOffset ;. is 1st Feb ! setDate date. setSeconds date. getTime - date1. getTime ; }. function diffSubtract date1, date2 { return date2 - date1; } function diffGetTime date1, date2 { return date2.

Be careful doing microbenchmarking. parse 'T Tasks Create a date. importance: 5. Create a Date object for the date: Feb 20, , am. The time zone is local. Show it using alert. So February has number 1. Show a weekday. The method date. getDay returns the number of the weekday, starting from sunday. European weekday. Which day of month was many days ago? importance: 4. The idea is simple: to substract given number of days from date : function getDateAgo date, days { date.

getDate - days ; return date. getDate ; }. getDate - days ; return dateCopy.
