10 * The date parsing and formatting syntax contains a subset of
11 * <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
12 * supported will provide results equivalent to their PHP versions.
14 * The following is a list of all currently supported formats:
16 Format Description Example returned values
17 ------ ----------------------------------------------------------------------- -----------------------
18 d Day of the month, 2 digits with leading zeros 01 to 31
19 D A short textual representation of the day of the week Mon to Sun
20 j Day of the month without leading zeros 1 to 31
21 l A full textual representation of the day of the week Sunday to Saturday
22 N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
23 S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
24 w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
25 z The day of the year (starting from 0) 0 to 364 (365 in leap years)
26 W ISO-8601 week number of year, weeks starting on Monday 01 to 53
27 F A full textual representation of a month, such as January or March January to December
28 m Numeric representation of a month, with leading zeros 01 to 12
29 M A short textual representation of a month Jan to Dec
30 n Numeric representation of a month, without leading zeros 1 to 12
31 t Number of days in the given month 28 to 31
32 L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
33 o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
34 belongs to the previous or next year, that year is used instead)
35 Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
36 y A two digit representation of a year Examples: 99 or 03
37 a Lowercase Ante meridiem and Post meridiem am or pm
38 A Uppercase Ante meridiem and Post meridiem AM or PM
39 g 12-hour format of an hour without leading zeros 1 to 12
40 G 24-hour format of an hour without leading zeros 0 to 23
41 h 12-hour format of an hour with leading zeros 01 to 12
42 H 24-hour format of an hour with leading zeros 00 to 23
43 i Minutes, with leading zeros 00 to 59
44 s Seconds, with leading zeros 00 to 59
45 u Decimal fraction of a second Examples:
46 (minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
49 999876543210 (i.e. 0.999876543210s)
50 O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
51 P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
52 T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
53 Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
56 1) If unspecified, the month / day defaults to the current month / day, 1991 or
57 the time defaults to midnight, while the timezone defaults to the 1992-10 or
58 browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
59 and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
60 are optional. 1995-07-18T17:21:28-02:00 or
61 2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
62 least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
63 of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
64 Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or
65 date-time granularity which are supported, or see 2000-02-13T21:25:33
66 http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
67 U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
68 M$ Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
69 \/Date(1238606590509+0800)\/
72 * Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
75 // 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
77 var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
78 document.write(dt.format('Y-m-d')); // 2007-01-10
79 document.write(dt.format('F j, Y, g:i a')); // January 10, 2007, 3:05 pm
80 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
83 * Here are some standard date/time patterns that you might find helpful. They
84 * are not part of the source of Date.js, but to use them you can simply copy this
85 * block of code into any script that is included after Date.js and they will also become
86 * globally available on the Date object. Feel free to add or remove patterns as needed in your code.
89 ISO8601Long:"Y-m-d H:i:s",
92 LongDate: "l, F d, Y",
93 FullDateTime: "l, F d, Y g:i:s A",

108 * <p>Developer-written, custom formats may be used by supplying both a formatting and a parsing function
109 * which perform to specialized requirements. The functions are stored in {@link #parseFunctions} and {@link #formatFunctions}.</p>
113 * Most of the date-formatting functions below are the excellent work of Baron Schwartz.
114 * (see http://www.xaprb.com/blog/2005/12/12/javascript-closures-for-runtime-efficiency/)
115 * They generate precompiled functions from format patterns instead of parsing and
116 * processing each pattern every time a date is formatted. These functions are available
117 * on every Date object.
123 * Global flag which determines if strict date parsing should be used.
124 * Strict date parsing will not roll-over invalid dates, which is the
125 * default behaviour of javascript Date objects.
126 * (see {@link #parseDate} for more information)
127 * Defaults to <tt>false</tt>.
