|

Format Description Example returned values
|

|
|
l A full textual representation of the day of the week Sunday to Saturday
|
|
N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
|
|
S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
|
|

n Numeric representation of a month, without leading zeros 1 to 12
|
|
t Number of days in the given month 28 to 31
|
|
L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
|
|
o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
|
|
belongs to the previous or next year, that year is used instead)
|
|
Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
|
|
y A two digit representation of a year Examples: 99 or 03
|

|
|
i Minutes, with leading zeros 00 to 59
|
|
s Seconds, with leading zeros 00 to 59
|
|
u Decimal fraction of a second Examples:
|
|
(minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
|
|

|
P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
|
|
T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
|
|
Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
|
|
c ISO 8601 date
|
|
Notes: Examples:
|
|
1) If unspecified, the month / day defaults to the current month / day, 1991 or
|
|
the time defaults to midnight, while the timezone defaults to the 1992-10 or
|
|
browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
|
|
and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
|
|
are optional. 1995-07-18T17:21:28-02:00 or
|
|
2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
|
|
least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
|
|
of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
|
|
Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or
|
|
date-time granularity which are supported, or see 2000-02-13T21:25:33
|
|
http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
|
|
U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
|
|
M$ Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
|
|
\/Date(1238606590509+0800)\/

* Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
|
|
* <pre><code>
|
|
// Sample date:
|
|
// 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
|
|
|
|
var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
|
|
document.write(dt.format('Y-m-d')); // 2007-01-10
|
|
document.write(dt.format('F j, Y, g:i a')); // January 10, 2007, 3:05 pm
|
|
document.write(dt.format('l, \\t\\he jS \\of F Y h:i:s A')); // Wednesday, the 10th of January 2007 03:05:01 PM
|
|
</code></pre>

|
|
* Here are some standard date/time patterns that you might find helpful. They
|
|
* are not part of the source of Date.js, but to use them you can simply copy this
|
|
* block of code into any script that is included after Date.js and they will also become
|
|
* globally available on the Date object. Feel free to add or remove patterns as needed in your code.
|
|
* <pre><code>
|
|
Date.patterns = {
|
|
ISO8601Long:"Y-m-d H:i:s",
|
|
ISO8601Short:"Y-m-d",
