// ['1 1 2012'] would disable January 1, 2012;

//
// default is 1, Monday
first_day_of_week: 1,
// format of the returned date
//
// accepts the following characters for date formatting: d, D, j, l, N, w, S, F, m, M, n, Y, y, h, H,
// g, G, i, s, a, A borrowing the syntax from PHP's "date" function.
//
// note that when setting a date format without days ('d', 'j'), the users will be able to select only years
// and months, and when setting a format without months and days ('F', 'm', 'M', 'n', 'd', 'j'), the
// users will be able to select only years; likewise, when setting a date format with just months ('F', 'm',
// 'M', 'n') or just years ('Y', 'y'), users will be able to select only months and years, respectively.
//
// setting a format that also involves time (h, H, g, G, i, s, a, A) will automatically enable the time
// picker. if you want to use a format that involves time but you don't want the time picker, set the
// "disable_time_picker" property to TRUE.
//
// setting a time format containing "a" or "A" (12-hour format) but using "H" or "G" as the hour's format
// will result in the hour's format being changed to "h" or "g", respectively.
//
// also note that the value of the "view" property (see below) may be overridden if it is the case: a value of
// "days" for the "view" property makes no sense if the date format doesn't allow the selection of days.
//
// default is Y-m-d
format: 'Y-m-d',
// captions in the datepicker's header, for the 3 possible views: days, months, years
//
// for each of the 3 views the following special characters may be used borrowing from PHP's "date" function's
// syntax: m, n, F, M, y and Y; any of these will be replaced at runtime with the appropriate date fragment,
// depending on the currently viewed date. two more special characters are also available Y1 and Y2 (upper
// case representing years with 4 digits, lowercase representing years with 2 digits) which represent
// "currently selected year - 7" and "currently selected year + 4" and which only make sense used in the
// "years" view.
//
// even though any of these special characters may be used in any of the 3 views, you should use m, n, F, M
// for the "days" view and y, Y, Y1, Y2, y1, y2 for the "months" and "years" view or you may get unexpected
// results!
//
// Text and HTML can also be used, and will be rendered as it is, as in the example below (the library is
// smart enough to not replace special characters when used in words or HTML tags):
//
// header_captions: {
// 'days': 'Departure:<br>F, Y',
// 'months': 'Departure:<br>Y',
// 'years': 'Departure:<br>Y1 - Y2'
// }
//

//
// default is FALSE

// if set to FALSE, the icon will be placed to the right of the parent element, while if set to TRUE it will

open_on_focus: false,

// picker again, this time the button will be visible.
//
// - TRUE will make the button visible all the time
//
// - FALSE will disable the button
//
// default is "0" (without quotes)
show_clear_date: 0,
// should a calendar icon be added to the elements the plugin is attached to?
