PHP's date in JavaScript

Here’s what our current JavaScript equivalent to PHP's date looks like.

How to use

You you can install via npm install locutus and require it via require('locutus/php/datetime/date'). You could also require the datetime module in full so that you could access instead.

If you intend to target the browser, you can then use a module bundler such as Browserify, webpack or rollup.js.


This function targets ES5, but as of Locutus 2.0.2 we also support ES6 functions. Locutus transpiles to ES5 before publishing to npm.

A community effort

Not unlike Wikipedia, Locutus is an ongoing community effort. Our philosophy follows The McDonald’s Theory. This means that we don't consider it to be a bad thing that many of our functions are first iterations, which may still have their fair share of issues. We hope that these flaws will inspire others to come up with better ideas.

This way of working also means that we don't offer any production guarantees, and recommend to use Locutus inspiration and learning purposes only.


  • Uses global: locutus to store the default timezone Although the function potentially allows timezone info (see notes), it currently does not set per a timezone specified by date_default_timezone_set(). Implementers might use $locutus.currentTimezoneOffset and $locutus.currentTimezoneDST set by that function in order to adjust the dates in this function (or our other date functions!) accordingly


Please note that these examples are distilled from test cases that automatically verify our functions still work correctly. This could explain some quirky ones.

#codeexpected result
1date('H:m:s \\m \\i\\s \\m\\o\\n\\t\\h', 1062402400)'07:09:40 m is month'
2date('F j, Y, g:i a', 1062462400)'September 2, 2003, 12:26 am'
3date('Y W o', 1062462400)'2003 36 2003'
4var $x = date('Y m d', (new Date()).getTime() / 1000) $x = $x + '' var $result = $x.length // 2009 01 0910
5date('W', 1104534000)'52'
6date('B t', 1104534000)'999 31'
7date('W U', 1293750000.82); // 2010-12-31'52 1293750000'
8date('W', 1293836400); // 2011-01-01'52'
9date('W Y-m-d', 1293974054); // 2011-01-02'52 2011-01-02'
