Date.Extras

docs

date.extras.js just adds some more functionality to the date.js extensions to the Date native. They are split up so that if you have something simple to implement that you want to keep the code small (like our Date Picker, you can only include the basic date.js.

Here's what you get with date.extras.js:

var example = new Date();
console.log(example.timeDiffInWords()); /* "less than a minute ago" */
example.decrement('hour');
console.log(example.timeDiffInWords()); /* "about an hour ago" */
example.increment('hour', 2);
console.log(example.timeDiffInWords()); /* "about an hour from now" */

Returns the ordinal for the day ("th", "nd", etc).

new Date().getOrdinal();

Returns the day of the year (so Dec 31 is 365 unless it's leap year).

Date.parse("12.31.1999").getDayOfYear(); //365

So for Dec you'd get 31.

var dec = new Date();
dec.setMonth(11);
dec.getLastDayOfMonth(); //31

Returns what week you're in of the year, so Dec 31 will return 52.

Date.parse("12.31.1999").getWeek(); //52

The biggest thing you get with date.extras.js is a whole bunch of parsers. date.js just includes the basics ("12/31/1999" and "12/31/1999 11:59pm"), while date.extras.js includes another ten.

Date.parse('1999-12-31 23:59:59')

Date.parse('1999-12-31T23:59:59+0200')

Date.parse('today')

Date.parse('tomorrow')

Date.parse('yesterday')

Date.parse('next monday')

Date.parse('1st')

Date.parse('14th October')

Date.parse('24th May, 2007')

Date.parse('May 3rd 2006')
