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.


Boolean. Default: false

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


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


Boolean. Default: false

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


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.


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].


Date. Default: End of time

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


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.


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.


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.


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.


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, Number. Default: false

Enable multidate picking. Each date in month view acts as a toggle button, keeping track of which dates the user has selected in order. If a number is given, the picker will limit how many dates can be selected to that number, dropping the oldest dates from the list when the number is exceeded. true equates to no limit. The input’s value (if present) is set to a string generated by joining the dates, formatted, with multidateSeparator.


String. Default: ”,”

The string that will appear between dates when generating the input’s value. When parsing the input’s value for a multidate picker, this will also be used to split the incoming string to separate multiple formatted dates; as such, it is highly recommended that you not use a string that could be a substring of a formatted date (eg, using ‘-‘ to separate dates when your format is ‘yyyy-mm-dd’).


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.


Date. Default: Beginning of time

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


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.


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.


Integer. Default: 0

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