jsCalendar is a lightweight date picker for desktop and mobile browsers.

• small file size
• designed for webkit mobile, mainly iOS and Android
• support for desktop browsers
• works with jQuery as well as Zepto.js
• range of days selection mode
• single date selection mode
• 3D calendar turn over css3 animation, supported by Safari only
• multilingual support
• flexible first day of the week
• multiple calendars on one page possible
• selecting past dates is prevented

• jQuery or Zepto.js
• Modernizr or the included Modernizr custom build using a reduced subset

On document ready, the calendar attaches itself to HTML elements with the class name "jsCalendar". Manual initialization is not necessary. This element should have an attribute data-localized_date with a JSON string as value containing the localized names of months and weekdays like this one:

{"days":{"names":{"min":["Sun","Mon","Tue","Wed","Thu","Fri","Sat"]}},"months":{"names":{"long":["January","February","March","April","May","June","July","August","September","October","November","December"]}}}

It is possible to select a range of days between start and end date as well as selecting a single date. Range selection is default. To switch to single date selection, add the class name jsSingleDate to the jsCalendar HTML element before document ready.

You are notified when the user changes the selection by the custom events startDateChanged and endDateChanged on the jsCalender HTML element. So the currently selected dates can be retrieved like this:

$(".jsCalendar").bind("startDateChanged", function() {
    $(this).data("startdate");
}).bind("endDateChanged", function() {
    $(this).data("enddate");
});

If you are using the single date selection mode, startDateChanged is the only triggered event.

To initialize the calendar with start and end date, specify the attributes data-startdate and data-enddate at the jsCalender HTML element with the string representation of a JavaScript Date object.

To set dates programatically, call $(".jsCalendar").calendar().setDates(start, end), where start and end are Date objects representing the dates you want to set. If you pass null as parameter, the corresponding date selection is removed.

To reset the selection programatically (e.g. with an extra button), you could trigger a resetSelection event on the jsCalender HTML element.

From the user's perspective, range selection works like this: the first click is the start date, second click the end date, a third click resets the selection. If the selected end date is before the start date, they are automatically exchanged. It is possible to deselect a start or end date by clicking it without resetting the whole selection. You can implement your own date selection algorithm by rewriting the dateSelected method.

To set the first day of the week (e.g: Sunday, Monday, ...) specify the attribute data-firstdayofweek at the jsCalender HTML element with a value between 0 and 6.

It is possible to display a specific month by calling $(".jsCalendar").calendar().showMonth(date), where date is a Date object representing the desired month.

Right now, it is not possible to select a date in the past and there is no maximum selection date for the far future.

After initialization, the JavaScript Date object will be extended with a subset of instance methods from datejs: clone, isLeapYear, getDaysInMonth, moveToFirstDayOfMonth, moveToLastDayOfMonth, addMilliseconds, addDays, addMonths and clearTime.

The $ function is extended with a slice method to select a range from a set of elements like this $("a").slice(3, 7), using the native slice implementation for arrays. Another extension is the calendar method, returning the Calendar object belonging to the first matched HTML element, if available.
