    A basic datepicker

    Date Formatting

    Using dateFormat

    <input class=flatpickr data-date-format="d-m-Y">
    <input class=flatpickr data-date-format="m/d/Y">
    <input class=flatpickr data-date-format="l, F j, Y">

    DateTime Picker

    <input class=flatpickr data-enable-time=true>

    DateTime Picker: 24 Hour Mode

    <input class=flatpickr data-enable-time=true data-time_24hr=true>

    DateTime Picker with seconds

    <input class=flatpickr data-enable-time=true data-enable-seconds=true >

    Time Picker

    <input class=flatpickr data-enable-time=true data-enable-seconds=true data-no-calendar=true value="09:01:45">
    <input class=flatpickr data-enable-time=true data-enable-seconds=true data-no-calendar=true value="09:01:30 PM">

    Date Limits - minDate and maxDate

    The example below conveniently uses data-attributes for setting minDate and maxDate options.
    <input class=flatpickr data-min-date=today>
    <input class=flatpickr data-min-date="2016-09-20">
    <input class=flatpickr data-min-date="September 2, 2015">
    <input class=flatpickr data-min-date=today data-max-date='2016-8-20'>

    Human-friendly Date Output

    altInput can be used for displaying a friendly date format (per altFormat) to the user while sending the date formatted as dateFormat to the server. Feel free to inspect the input element below after picking a date to see what's going on.

    <input class=flatpickr data-alt-input=true data-alt-format="F j, Y">

    Selected date: nothing yet

    Preload date and time

    You may load the calendar with a predefined value, ranging from simple dates, such as "2016-04-10" to full-fledged datetime strings. To keep the dates in UTC/GMT, see the UTC option.

    <input type=text class=flatpickr data-enable-time=true value="Sun, 24 Jul 2016 05:16:47 GMT">

    <input class=flatpickr data-default-date="2016-12-27T16:16:22.585Z" data-enable-time=true>

    Custom elements and input groups

    flatpickr can parse an input group of textboxes and buttons, common in Bootstrap and other frameworks.

    This permits additional markup, as well as custom elements to trigger the state of the calendar.

    Mark your input element with data-input (mandatory), and any additional buttons with data-toggle, data-open, data-close, or data-clear.

    <p class="flatpickr" data-wrap="true" data-click-opens="false">
    	<input placeholder="Pick date" data-input>
    	<a class="input-btn" data-toggle><i class="icon-calendar"></i></a>
    	<a class="input-btn" data-clear><i class="icon-close"></i></a>

    Disabling dates

    Disable a date interval, or a specific date.

    	disable: [
    			from: "2016-08-16",
    			to: "2016-08-19"
    		new Date().fp_incr(30) // 30 days from now

    Or pass in a custom function and disable dates using any logic you want.

    	disable: [
    		function(date){ // disable odd days
    			return date.getDate()%2 > 0;

    Disable all dates except the ones you need, by passing in date strings, Date objects, or functions.

    	enable: [
    			from: "today",
    			to: new Date().fp_incr(7) // 7 days from now

    Use custom logic to enable the dates you need. For instance, enable business days of 2016:

    	enable: [
    			return dateObj.getDay() %6 !== 0 && dateObj.getFullYear() === 2016;

    Allowing manual input

    You may let your users input dates themselves simply by toggling the allowInput option

    <input type=text class=flatpickr data-enable-time=true data-allow-input=true">

    UTC mode

    By default, JavaScript's Date converts all dates to a local time. However, locale-agnostic databases often store dates in UTC. flatpickr can convert any given dates to UTC and select a datetime in UTC with a simple switch. Here are the previous examples with UTC mode enabled.

    <input class=flatpickr data-utc=true data-default-date="1994-11-05 09:15:30 GMT" data-enable-time=true>

    <input class=flatpickr data-default-date="2016-12-27T16:16:22.585Z" data-utc=true data-enable-time=true>

    Event API

    	minDate: "today",
    	enableTime: true,
    	onChange: function(dateObj, dateStr, instance) {
    	onOpen: function(dateObj, dateStr, instance){
    	onClose: function(dateObj, dateStr, instance){

    Example: check in and check out

    var check_in = document.getElementById("check_in_date").flatpickr({
    	altInput: true,
    	altFormat: "\\C\\h\\e\\c\\k \\i\\n\\: l, F j Y",
    	minDate: new Date()
    var check_out = document.getElementById("check_out_date").flatpickr({
    	altInput: true,
    	altFormat: "\\C\\h\\e\\c\\k \\o\\u\\t: l, F j Y",
    	minDate: new Date()
    check_in.config.onChange = dateObj => check_out.set("minDate", dateObj.fp_incr(1));
    check_out.config.onChange = dateObj => check_in.set("maxDate", dateObj.fp_incr(-1));

    Display week numbers

    <input class=flatpickr data-week-numbers=true placeholder="Enabled week numbers">

    Fiscal Calendar

    You may override the getWeek() function, used for calculating a week number, for various purposes. A fiscal year is used for calculating yearly financial statements. In this example, we will use override the getWeek() function to display the fiscal term instead of the usual week numbers.

    <input id="fiscal" placeholder="Fiscal Calendar">
    Flatpickr.prototype.getWeek = function(givenDate){
    	var checkDate = new Date(givenDate.getTime());
    	checkDate.setDate(checkDate.getDate() + 4 - (checkDate.getDay() || 7));
    	var time = checkDate.getTime();
    	var week = (Math.floor(Math.round((time - checkDate) / 86400000) / 7) + 2);
    	if (week < 1) {
    		week = 52 + week;
    	return 'FW'+week;
    	weekNumbers: true

    Inline or embedded calendar

    <input class=flatpickr data-inline=true placeholder="Pick a date below">

    Customizing default options

    // use your own arrow icons
    Flatpickr.defaultConfig.prevArrow = "<i class='icon i-angle-left'></i>";
    Flatpickr.defaultConfig.nextArrow = "<i class='icon i-angle-right'></i>";
    // change the first day of the week to Monday
    Flatpickr.l10n.firstDayOfWeek = 1;
    // then initialize your calendars


    Protip: all of the string/boolean config options can also be supplied using data attributes, e.g. data-min-date, data-default-date, data-date-format etc.

    Config Option Type Default Description
    altFormat string "F j, Y" Exactly the same as date format, but for the altInput field
    altInput Boolean false Show the user a readable date (as per altFormat), but return something totally different to the server.
    altInputClass String "" This class will be added to the input element created by the altInput option. Helpful if input elements are styled using classes. Bootstrap users will want to specify form-control here.
    allowInput boolean false Allows the user to enter a date directly input the input field. By default, direct entry is disabled.
    clickOpens boolean true Clicking on the input opens the date (time) picker. Disable this if you wish to open the calendar manually with .open()
    dateFormat string "Y-m-d" A string of characters which are used to define how the date will be displayed in the input box. The supported characters are defined in the table below.
    defaultDate String/Date Object null Set the initial selected date. Same as preloading a date string into an input's value attribute, but can also handle a Date object.
    disable array [] Dates to disable, using intervals
    enableTime boolean false Enables time picker
    enableSeconds boolean false Enables seconds in the time picker.
    noCalendar boolean false Hides the calendar. For use along with enableTime.
    hourIncrement integer 1 Adjusts the step for the hour input (incl. scrolling)
    minuteIncrement integer 5 Adjusts the step for the minute input (incl. scrolling)
    inline boolean false Displays the calendar inline. See Inline or embedded calendar.
    static boolean false Position the calendar inside the wrapper and next to the input element. (Leave false unless you know what you're doing.
    wrap Boolean false The wrapping element. See Custom elements and input groups.
    maxDate String null The maximum date that a user can pick to, as a string.
    See Date.parse()
    minDate String null The minimum date that a user can start picking from, as a string.
    See Date.parse()
    onChange function(dateObject, dateString) null A function that gets triggered on every date selection
    onOpen function(dateObject, dateString) null A function that gets triggered on every time the calendar is opened.
    onClose function(dateObject, dateString) null A function that gets triggered on every time the calendar is closed.
    parseDate function false A function that expects a date string and must return a Date object
    shorthandCurrentMonth boolean false Show the month using the shorthand version (ie, Sep instead of September).
    weekNumbers boolean false Enables display of week numbers in calendar.
    time_24hr boolean false Displays time picker in 24 hour mode without AM/PM selection when enabled.
    utc boolean false When true, dates will parsed, formatted, and displayed in UTC. It's recommended that date strings contain the timezone, but not necessary.
    prevArrow string < Code for the previous icon.
    nextArrow string > Code for the next icon.

    Date Format Characters

    Character Description Example
    d Day of the month, 2 digits with leading zeros 01 to 31
    D A textual representation of a day Mon through Sun
    l (lowercase 'L') A full textual representation of the day of the week Sunday through Saturday
    j Day of the month without leading zeros 1 to 31
    J Day of the month without leading zeros and ordinal suffix 1st, 2nd, to 31st
    w Numeric representation of the day of the week 0 (for Sunday) through 6 (for Saturday)
    F A full textual representation of a month January through December
    m Numeric representation of a month, with leading zero 01 through 12
    n Numeric representation of a month, without leading zeros 1 through 12
    M A short textual representation of a month Jan through Dec
    U The number of seconds since the Unix Epoch 1413704993
    y A two digit representation of a year 99 or 03
    Y A full numeric representation of a year, 4 digits 1999 or 2003

    Time Format Characters

    Character Description Example
    H Hours (24 hours) 00 to 23
    h Hours 1 to 12
    i Minutes 00 to 59
    S Seconds, 2 digits 00 to 59
    s Seconds 0, 1 to 59
    K AM/PM AM or PM

    Escaping date format characters

    To escape a character (if you need to use one of the reserved format characters above) use a double backslash: \\


    dateFormat: '\\D\\a\\y \\p\\i\\c\\k\\e\\d: Y/m/d'

    To get something like:

    Day picked: 2013/02/12

    If you do not escape the characters you would end up with something like this instead:

    Tuea13 picke12: 2013/02/12

    Which is probably not what you want...

    Note: It's recommended that you escape all characters that you don't want accidentally converted to format characters in the future as others are added.
