4 The following is a list of all currently supported formats:
6 Format Description Example returned values
7 ------ ----------------------------------------------------------------------- -----------------------
8 d Day of the month, 2 digits with leading zeros 01 to 31

11 l A full textual representation of the day of the week Sunday to Saturday
12 N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
13 S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
14 w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
15 z The day of the year (starting from 0) 0 to 364 (365 in leap years)
16 W ISO-8601 week number of year, weeks starting on Monday 01 to 53
17 F A full textual representation of a month, such as January or March January to December

22 L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
23 o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
24 belongs to the previous or next year, that year is used instead)

36 (minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
39 999876543210 (i.e. 0.999876543210s)
40 O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
41 P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
42 T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
43 Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
46 1) If unspecified, the month / day defaults to the current month / day, 1991 or
47 the time defaults to midnight, while the timezone defaults to the 1992-10 or
48 browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
49 and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
50 are optional. 1995-07-18T17:21:28-02:00 or
51 2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
52 least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
53 of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
54 Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or

57 U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
58 M$ Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
59 \/Date(1238606590509+0800)\/
61 Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
62 <pre><code><i>// Sample date:</i>
63 <i>// <em>'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'</em></i>
65 <b>var</b> dt = <b>new</b> Date(<em>'1/10/2007 03:05:01 PM GMT-0600'</em>);
66 document.write(dt.format(<em>'Y-m-d'</em>)); <i>// 2007-01-10</i>
67 document.write(dt.format(<em>'F j, Y, g:i a'</em>)); <i>// January 10, 2007, 3:05 pm</i>
68 document.write(dt.format(<em>'l, \\t\\he jS \\of F Y h:i:s A'</em>)); <i>// Wednesday, the 10th of January 2007 03:05:01 PM</i></code></pre>
69 Here are some standard date/time patterns that you might find helpful. They
70 are not part of the source of Date.js, but to use them you can simply copy this
71 block of code into any script that is included after Date.js and they will also become
72 globally available on the Date object. Feel free to add or remove patterns as needed in your code.
73 <pre><code>Date.patterns = {
74 ISO8601Long:<em>"Y-m-d H:i:s"</em>,
75 ISO8601Short:<em>"Y-m-d"</em>,
