For three months ago I added Chuvash localization of moment.js. For 16 days ago moment.js 1.7.0 was officially released which included the Chuvash translation.

Wait a sec… What is moment.js?

moment.js is the best datetime tool for javascript. It supports many languages (now even Chuvash) for displaying date and time. Another very handy functionality is showing relative time which has a simple interface: fromNow(). Here is a simple example from a web browser console:

Just look at moment.js. Everybody who have worked with dates in javascript are going to love it.

Interesting, I hadn’t heard of moment.js. I’m taking a look at the site right now; it looks to have some very handy functionality for date manipulation!

The great thing with moment.js is e.g. that one can create a date object from asp.net date format like /Date(123543534)/

An alternative to jQuery UI datepicker is Kalendae. (MIT License). Highly customizable and no dependencies to other javascript libraries. Here is the highlights:

Kalendae is an attempt to do something that nobody has yet been able to do: make a date picker that doesn’t suck. Kalendae provides the following features:

1. Fully portable, no dependencies. No jQuery, no Prototype, no MooTools; just add the script and the stylesheet and you’re good to go.
2. Fully and easily skinable. The default theme uses only one image file (a mask for the previous and next buttons), everything else is styled using CSS.
3. Supports all modern browsers and IE8.
4. Support single day, multiple day, or day range selection.
5. Configurable number of months to be displayed at once.
6. Can be displayed on the page as an inline widget, or attached to one or more input fields as a popup control.
7. Can be attached to any page element, not just named elements.
8. Configurable blackouts, defined either as an array of dates or via a callback function
9. Output selected dates in a variety of formats
10. Leverages moment.js for smart and easy date parsing.

Found through daily.js

There is a solution in StackOverflow:

/\* use a function for the exact format desired... \*/
function ISODateString(d){
 function pad(n){return n<10 ? '0'+n : n}
 return d.getUTCFullYear()+'-'
      + pad(d.getUTCMonth()+1)+'-'
      + pad(d.getUTCDate())+'T'
      + pad(d.getUTCHours())+':'
      + pad(d.getUTCMinutes())+':'
      + pad(d.getUTCSeconds())+'Z'}

var d = new Date();
print(ISODateString(d)); // prints something like 2009-09-28T19:03:12Z
```But there is already a function for this: toISOString, it came with ecmascript 5. [Unfortunately, not all browsers support this](http://kangax.github.com/es5-compat-table/ "See the best comparision for ecmascript 5 support"), to solve this problem, we can provide our own prototype function for Date if it doesn't exist:

if (!Date.prototype.toISOString) { Date.prototype.toISOString = function() { function pad(n) { return n < 10 ? ‘0’ + n : n } return this.getUTCFullYear() + ‘-’ + pad(this.getUTCMonth() + 1) + ‘-’ + pad(this.getUTCDate()) + ‘T’ + pad(this.getUTCHours()) + ‘:’ + pad(this.getUTCMinutes()) + ‘:’ + pad(this.getUTCSeconds()) + ‘Z’; }; }
