You can install Pikaday as an NPM package:

npm install pikaday

You will also need to include Pikaday CSS file. This step depends on how Pikaday was installed. Either import from NPM:

@import './node_modules/pikaday/css/pikaday.css';

Pikaday can be bound to an input field:

<input type="text" id="datepicker">

Add the JavaScript to the end of your document:

<script src="pikaday.js"></script>
<script>
    var picker = new Pikaday({ field: document.getElementById('datepicker') });
</script>

If you're using jQuery make sure to pass only the first element:

var picker = new Pikaday({ field: $('#datepicker')[0] });

If the Pikaday instance is not bound to a field you can append the element anywhere:

var field = document.getElementById('datepicker');
var picker = new Pikaday({
    onSelect: function(date) {
        field.value = picker.toString();
    }
});
field.parentNode.insertBefore(picker.el, field.nextSibling);

By default, dates are formatted and parsed using standard JavaScript Date object. If [Moment.js][moment] is available in scope, it will be used to format and parse input values. You can pass an additional format option to the configuration which will be passed to the moment constructor. See the [moment.js example][] for a full version.

<input type="text" id="datepicker" value="9 Oct 2014">

<script src="moment.js"></script>
<script src="pikaday.js"></script>
<script>
    var picker = new Pikaday({
        field: document.getElementById('datepicker'),
        format: 'D MMM YYYY',
        onSelect: function() {
            console.log(this.getMoment().format('Do MMMM YYYY'));
        }
    });
</script>

For more advanced and flexible formatting you can pass your own toString function to the configuration which will be used to format the date object. This function has the following signature:

toString(date, format = 'YYYY-MM-DD')

You should return a string from it.

Be careful, though. If the formatted string that you return cannot be correctly parsed by the Date.parse method, then you must provide your own parse function in the config. This function will be passed the formatted string and the format:

parse(dateString, format = 'YYYY-MM-DD')

var picker = new Pikaday({
    field: document.getElementById('datepicker'),
    format: 'D/M/YYYY',
    toString(date, format) {
        // you should do formatting based on the passed format,
        // but we will just return 'D/M/YYYY' for simplicity
        const day = date.getDate();
        const month = date.getMonth() + 1;
        const year = date.getFullYear();
        return `${day}/${month}/${year}`;
    },
    parse(dateString, format) {
        // dateString is the result of `toString` method
        const parts = dateString.split('/');
        const day = parseInt(parts[0], 10);
        const month = parseInt(parts[1], 10) - 1;
        const year = parseInt(parts[2], 10);
        return new Date(year, month, day);
    }
});

As the examples demonstrate above Pikaday has many useful options:

• field bind the datepicker to a form field
• trigger use a different element to trigger opening the datepicker, see trigger example (default to field)
• bound automatically show/hide the datepicker on field focus (default true if field is set)
• debounce delays update of Pickaday window when adjusting text field
• ariaLabel data-attribute on the input field with an aria assistance text (only applied when bound is set)
• position preferred position of the datepicker relative to the form field, e.g.: top right, bottom right Note: automatic adjustment may occur to avoid datepicker from being displayed outside the viewport, see positions example (default to 'bottom left')
• reposition can be set to false to not reposition datepicker within the viewport, forcing it to take the configured position (default: true)
• container DOM node to render calendar into, see container example (default: undefined)
• format the default output format for .toString() and field value
• toString(date, format) function which will be used for custom formatting. This function will take precedence over moment.
• parse(dateString, format) function which will be used for parsing input string and getting a date object from it. This function will take precedence over moment.
• defaultDate the initial date to view when first opened
• setDefaultDate Boolean (true/false). make the defaultDate the initial selected value
• firstDay first day of the week (0: Sunday, 1: Monday, etc)
• minDate the minimum/earliest date that can be selected (this should be a native Date object - e.g. new Date() or moment().toDate())
• maxDate the maximum/latest date that can be selected (this should be a native Date object - e.g. new Date() or moment().toDate())
• yearOrder the sorted order of the years displayed in the dropdown - e.g. ascending or descending, (default ascending)
• disableWeekends disallow selection of Saturdays or Sundays
• disableDayFn callback function that gets passed a Date object for each day in view. Should return true to disable selection of that day.
• selectDayFn callback function that gets passed a Date object for each day in view. Should return true to select that day.
• yearRange number of years either side (e.g. 10) or array of upper/lower range (e.g. [1900,2015])
• showWeekNumber show the ISO week number at the head of the row (default false)
• pickWholeWeek select a whole week instead of a day (default false)
• isRTL reverse the calendar for right-to-left languages
• i18n language defaults for month and weekday names (see internationalization below)
• yearSuffix additional text to append to the year in the title
• showMonthAfterYear render the month after year in the title (default false)
• showDaysInNextAndPreviousMonths render days of the calendar grid that fall in the next or previous months (default: false)
• convertDateToMinOrMaxDate If minDate or maxDate is supplied then by default setDate function will convert date to minDate, if passed date is less than minDate, or convert date to maxDate, if passed date is greater than maxDate. Set this to false if you dont want this behaviour. (default: true)
• enableSelectionDaysInNextAndPreviousMonths allows user to select date that is in the next or previous months (default: false)
• numberOfMonths number of visible calendars (default: 1, maximum: 4)
• mainCalendar when numberOfMonths is used, this will help you to choose where the main calendar will be (default left, can be set to right). Only used for the first display or when a selected date is not already visible
• events array of dates that you would like to differentiate from regular days (e.g. ['Sat Jun 28 2017', 'Sun Jun 29 2017', 'Tue Jul 01 2017',])
• theme define a classname that can be used as a hook for styling different themes, see theme example (default null)
• blurFieldOnSelect defines if the field is blurred when a date is selected (default true)
• onSelect callback function for when a date is selected
• onOpen callback function for when the picker becomes visible
• onClose callback function for when the picker is hidden
• onDraw callback function for when the picker draws a new month
• onPaginate callback function for the prevMonth and nextMonth methods, also fired when the pagination is clicked
• keyboardInput enable keyboard input support (default true)
• disabledDays array of dates that you would like to disable (e.g. ['Sat Jun 28 2017', 'Sun Jun 29 2017', 'Tue Jul 01 2017',])
• enabledDays array of dates that you would like to be enabled, the rest of the days will be disabled (e.g. ['Sat Jun 28 2017', 'Sun Jun 29 2017', 'Tue Jul 01 2017',])

If the reposition configuration-option is enabled (default), Pikaday will apply CSS-classes to the datepicker according to how it is positioned:

• top-aligned
• left-aligned
• right-aligned
• bottom-aligned

Note that the DOM element at any time will typically have 2 CSS-classes (eg. top-aligned right-aligned etc).

You can control the date picker after creation:

var picker = new Pikaday({ field: document.getElementById('datepicker') });

picker.toString('YYYY-MM-DD')

Returns the selected date in a string format.

You can also provide your own toString function and do the formatting yourself. Read more in the formatting section. If toString function is not provided, JavaScript's default .toDateString() method will be used.

picker.getDate()

Returns a basic JavaScript Date object of the selected day, or null if no selection.

picker.setDate('2015-01-01')

Set the current selection. This will be restricted within the bounds of minDate and maxDate options if they're specified. You can optionally pass a boolean as the second parameter to prevent triggering of the onSelect callback (true), allowing the date to be set silently

picker.clear()

Will clear and reset the input where picker is bound to.

picker.gotoDate(new Date(2014, 1))

Change the current view to see a specific date. This example will jump to February 2014 (month is a zero-based index).

picker.gotoToday()

Shortcut for picker.gotoDate(new Date())

picker.gotoMonth(2)

Change the current view by month (0: January, 1: Februrary, etc).

picker.nextMonth() picker.prevMonth()

Go to the next or previous month (this will change year if necessary).

picker.gotoYear()

Change the year being viewed.

picker.setMinDate()

Update the minimum/earliest date that can be selected.

picker.setMaxDate()

Update the maximum/latest date that can be selected.

picker.setStartRange()

Update the range start date. For using two Pikaday instances to select a date range.

picker.setEndRange()

Update the range end date. For using two Pikaday instances to select a date range.

picker.isVisible()

Returns true or false.

picker.show()

Make the picker visible.

picker.adjustPosition()

Recalculate and change the position of the picker.

picker.hide()

Hide the picker making it invisible.

picker.destroy()

Hide the picker and remove all event listeners — no going back!

The default i18n configuration format looks like this:

i18n: {
    previousMonth : 'Previous Month',
    nextMonth     : 'Next Month',
    months        : ['January','February','March','April','May','June','July','August','September','October','November','December'],
    weekdays      : ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
    weekdaysShort : ['Sun','Mon','Tue','Wed','Thu','Fri','Sat']
}

You must provide 12 months and 7 weekdays (with abbreviations). Always specify weekdays in this order with Sunday first. You can change the firstDay option to reorder if necessary (0: Sunday, 1: Monday, etc). You can also set isRTL to true for languages that are read right-to-left.

Pikaday is a pure datepicker. It will not support picking a time of day. However, there have been efforts to add time support to Pikaday. See #1 and #18. These reside in their own fork.

You can use the work @owenmead did most recently at owenmead/Pikaday A more simple time selection approach done by @xeeali at xeeali/Pikaday is based on version 1.2.0. Also @stas has a fork stas/Pikaday, but is now quite old
