This is a fork of Stefan Petre's original code; thanks go to him for getting this thing started!

Please note that this fork is not used on Stefan's page at this time, nor is it maintained or contributed to by him (yet?)

Versions are incremented according to semver.

Online Demo

• Bootstrap 2.0.4+
• jQuery 1.7.1+

These are the specific versions bootstrap-datepicker is tested against (js files) and built against (css files). Use other versions at your own risk.

Attached to a field with the format specified via options:

<input type="text" value="02-16-2012" class="datepicker">

$('.datepicker').datepicker({
    format: 'mm-dd-yyyy'
});

Attached to a field with the format specified via data tag:

<input type="text" value="02/16/12" data-date-format="mm/dd/yy" class="datepicker" >

$('.datepicker').datepicker();

As component:

<div class="input-append date datepicker" data-date="12-02-2012" data-date-format="dd-mm-yyyy">
    <input size="16" type="text" value="12-02-2012" readonly><span class="add-on"><i class="icon-th"></i></span>
</div>

$('.datepicker').datepicker();

Attached to non-field element, using events to work with the date values.

<div class="alert alert-error" id="alert">
    <strong>Oh snap!</strong>
</div>
<table class="table">
    <thead>
        <tr>

As inline datepicker:

<div class="datepicker"></div>

$('.datepicker').datepicker();

Call the datepicker via javascript:

$('.datepicker').datepicker()

Requires bootstrap's dropdown component (dropdowns.less) for some styles.

A standalone .css file (including necessary dropdown styles) can be generated by running build/build_standalone.less through the lessc compiler:

$ lessc build/build_standalone.less datepicker.css

As with bootstrap's own plugins, datepicker provides a data-api that can be used to instantiate datepickers without the need for custom javascript. For most datepickers, simply set data-provide="datepicker" on the element you want to initialize, and it will be intialized lazily, in true bootstrap fashion. For inline datepickers, this can alternatively be data-provide="datepicker-inline"; these will be immediately initialized on page load, and cannot be lazily loaded.

You can disable datepicker's data-api in the same way as you would disable other bootstrap plugins:

$(document).off('.datepicker.data-api');

var datepicker = $.fn.datepicker.noConflict(); // return $.fn.datepicker to previously assigned value
$.fn.bootstrapDP = datepicker;                 // give $().bootstrapDP the bootstrap-datepicker functionality

All options that take a "Date" can handle a Date object; a String formatted according to the given format; or a timedelta relative to today, eg '-1d', '+6m +1y', etc, where valid units are 'd' (day), 'w' (week), 'm' (month), and 'y' (year).

Most options can be provided via data-attributes. An option can be converted to a data-attribute by taking its name, replacing each uppercase letter with its lowercase equivalent preceded by a dash, and prepending "data-date-" to the result. For example, startDate would be data-date-start-date, format would be data-date-format, and daysOfWeekDisabled would be data-date-days-of-week-disabled.

String. Default: 'mm/dd/yyyy'

The date format, combination of d, dd, D, DD, m, mm, M, MM, yy, yyyy.

• d, dd: Numeric date, no leading zero and leading zero, respectively. Eg, 5, 05.
• D, DD: Abbreviated and full weekday names, respectively. Eg, Mon, Monday.
• m, mm: Numeric month, no leading zero and leading zero, respectively. Eg, 7, 07.
• M, MM: Abbreviated and full month names, respectively. Eg, Jan, January
• yy, yyyy: 2- and 4-digit years, respectively. Eg, 12, 2012.

Integer. Default: 0

Day of the week start. 0 (Sunday) to 6 (Saturday)

Boolean. Default: false

Whether or not to show week numbers to the left of week rows.

Date. Default: Beginning of time

The earliest date that may be selected; all earlier dates will be disabled.

Date. Default: End of time

The latest date that may be selected; all later dates will be disabled.

String, Array. Default: '', []

Days of the week that should be disabled. Values are 0 (Sunday) to 6 (Saturday). Multiple values should be comma-separated. Example: disable weekends: '0,6' or [0,6].

Boolean. Default: false

Whether or not to close the datepicker immediately when a date is selected.

Number, String. Default: 0, 'month'

The view that the datepicker should show when it is opened. Accepts values of 0 or 'month' for month view (the default), 1 or 'year' for the 12-month overview, and 2 or 'decade' for the 10-year overview. Useful for date-of-birth datepickers.

Number, String. Default: 0, 'days'

Set a limit for the view mode. Accepts: 'days' or 0, 'months' or 1, and 'years' or 2. Gives the ability to pick only a month or an year. The day is set to the 1st for 'months', and the month is set to January for 'years'.

Boolean, "linked". Default: false

If true or "linked", displays a "Today" button at the bottom of the datepicker to select the current date. If true, the "Today" button will only move the current date into view; if "linked", the current date will also be selected.

Boolean. Default: false

If true, highlights the current date.

Boolean. Default: false

If true, displays a "Clear" button at the bottom of the datepicker to clear the input value. If "autoclose" is also set to true, this button will also close the datepicker.

Boolean. Default: true

Whether or not to allow date navigation by arrow keys.

String. Default: 'en'

The IETF code (eg "en" for English, "pt-BR" for Brazilian Portuguese) of the language to use for month and day names. These will also be used as the input's value (and subsequently sent to the server in the case of form submissions). If a full code (eg "de-DE") is supplied the picker will first check for an "de-DE" language and if not found will fallback and check for a "de" language. If an unknown language code is given, English will be used. See I18N below.

Boolean. Default: true

Whether or not to force parsing of the input value when the picker is closed. That is, when an invalid date is left in the input field by the user, the picker will forcibly parse that value, and set the input's value to the new, valid date, conforming to the given format.

Array. Default: None

A list of inputs to be used in a range picker, which will be attached to the selected element. Allows for explicitly creating a range picker on a non-standard element.

Function(Date). Default: $.noop

A function that takes a date as a parameter and returns one of the following values:

• undefined to have no effect
• A Boolean, indicating whether or not this date is selectable
• A String representing additional CSS classes to apply to the date's cell
• An object with the following properties:
  • enabled: same as the Boolean value above
  • classes: same as the String value above
  • tooltip: a tooltip to apply to this date, via the title HTML attribute

String. Default: "auto"

A space-separated string consisting of one or two of "left" or "right", "top" or "bottom", and "auto" (may be omitted); for example, "top left", "bottom" (horizontal orientation will default to "auto"), "right" (vertical orientation will default to "auto"), "auto top". Allows for fixed placement of the picker popup.

"orientation" refers to the location of the picker popup's "anchor"; you can also think of it as the location of the trigger element (input, component, etc) relative to the picker.

"auto" triggers "smart orientation" of the picker. Horizontal orientation will default to "left" and left offset will be tweaked to keep the picker inside the browser viewport; vertical orientation will simply choose "top" or "bottom", whichever will show more of the picker in the viewport.

Format a component.

<div class="input-append date datepicker" data-date="12-02-2012" data-date-format="dd-mm-yyyy">
    <input class="span2" size="16" type="text" value="12-02-2012"><span class="add-on"><i class="icon-th"></i></span>
</div>

Create a date-range picker:

<div class="input-daterange" id="datepicker">
    <input class="input-small" name="start" value="2012-04-05" />
    <span class="add-on">to</span>
    <input class="input-small" name="end" value="2012-04-07" />
</div>

Sets a new lower date limit on the datepicker.

$('.datepicker').datepicker('setStartDate', '2012-01-01');

Omit startDate (or provide an otherwise falsey value) to unset the limit.

$('.datepicker').datepicker('setStartDate');
$('.datepicker').datepicker('setStartDate', null);

Arguments:

• endDate (Date)

Sets a new upper date limit on the datepicker.

$('.datepicker').datepicker('setEndDate', '2012-12-31');

Omit endDate (or provide an otherwise falsey value) to unset the limit.

$('.datepicker').datepicker('setDaysOfWeekDisabled', [0,6]);

Omit daysOfWeekDisabled (or provide an otherwise falsey value) to unset the disabled days.

$('.datepicker').datepicker('setDaysOfWeekDisabled');
$('.datepicker').datepicker('setDaysOfWeekDisabled', null);

Datepicker triggers a number of events in certain circumstances. All events have extra data attached to the event object that is passed to any event handlers:

$('.datepicker').datepicker()
    .on(picker_event, function(e){
        # `e` here contains the extra attributes
    });

• date: the relevant Date object, in local timezone.
• format([format]): a function to make formatting date easier. format can be any format string that datepicker supports. If format is not given, the format set on the datepicker will be used.

Fired when the date picker is displayed.

Fired when the date picker is hidden.

Fired when the date is cleared, normally when the "clear" button (enabled with the clearBtn option) is pressed.

Fired when the date is changed.

Fired when the view year is changed from decade view.

Fired when the view month is changed from year view.

The datepicker includes some keyboard navigation:

By themselves, left/right will move backward/forward one day, up/down will move back/forward one week.

With the shift key, up/left will move backward one month, down/right will move forward one month.

With the ctrl key, up/left will move backward one year, down/right will move forward oone year.

Shift+ctrl behaves the same as ctrl -- that is, it does not change both month and year simultaneously, only the year.

The escape key can be used to hide and re-show the datepicker; this is necessary if the user wants to manually edit the value.

When the picker is visible, enter will simply hide it. When the picker is not visible, enter will have normal effects -- submitting the current form, etc.

The plugin supports i18n for the month and weekday names and the weekStart option. The default is English ('en'); other available translations are avilable in the js/locales/ directory, simply include your desired locale after the plugin. To add more languages, simply add a key to $.fn.datepicker.dates, before calling .datepicker(). Example:

$.fn.datepicker.dates['en'] = {
    days: ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"],
    daysShort: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
    daysMin: ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa", "Su"],
    months: ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"],
    monthsShort: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
    today: "Today"
};

Right-to-left languages may also include rtl: true to make the calendar display appropriately.

If your browser (or those of your users) is displaying characters wrong, chances are the browser is loading the javascript file with a non-unicode encoding. Simply add charset="UTF-8" to your script tag:

<script type="text/javascript" src="bootstrap-datepicker.XX.js" charset="UTF-8"></script>

$('.datepicker').datepicker({
    language: XX    //as you defined in bootstrap-datepicker.XX.js
});
