I am trying to add tooltip on some disabled dates as holiday reason but unable get them displayed when hovered. i have even tried adding custom hover function but no success.

availableDates = ["09/04/2018", "09/05/2018", "09/06/2018", "08/31/2018", "09/01/2018"];
holidays_dates = "09/02/2018": "sgsdf", "05/27/2018": "home sick", "08/20/2018": "fcg", "05/26/2018": "i dont know", "05/25/2018": "home sick" 

function available(date) 

 var moth = String(date.getMonth() + 1);
 if (moth.length == 1) 
 moth = "0" + moth;
 

 var dat = String(date.getDate());
 if (dat.length == 1) 
 dat = "0" + dat;
 
 dmy = moth + "/" + dat + "/" + date.getFullYear();

 if ($.inArray(dmy, availableDates) != -1) 
 return [true, ""];
 else if (dmy in holidays_dates) 
 console.log(dmy)
 return [false, "Highlighted", holidays_dates[dmy]];
 else 
 return [false, ""];
 



$("#datepicker").datepicker(
 beforeShowDay: function (dt) 
 return available(dt);
 ,
 changeMonth: true,
 changeYear: true,
 onSelect: function (dateText) 
 getslots(dateText, selected_consultant);
 
);

the holidays_dates variable consists of disabled date and reason and is perfectly adding the reason to the title of the element

<td class=" ui-datepicker-unselectable ui-state-disabled Highlighted" title="home sick">
 <span class="ui-state-default">25</span>
</td>

as above holiday reason added in title attribute of tag but hovering on that date does not show tooltip

To disable the date and show tooltip use option beforeShowDay.

beforeShowDay: function (date) 
 var formattedDate = $.datepicker.formatDate('mm/dd/yy', date),
 checkDisable = disabledDates.indexOf(formattedDate) == -1;

 if(checkDisable == true)
 return [checkDisable];
 else
 //add ui-datepicker-unselectable class to the disabled date.
 return [!checkDisable,'ui-datepicker-unselectable',holidays_dates[formattedDate]];
 

and customize the css of the disabled date

function changeDisableDateColor()
var unselectableDate = $('.ui-datepicker-unselectable a');

unselectableDate.css(
 background: 'red',
 cursor: 'context-menu',
 border: 0
);

call the above function i.e changeDisableDateColor when date field is clicked.
$('#datepicker').click(function()
changeDisableDateColor();
);

and also inside onChangeMonthYear (detects the change in month or year) option

onChangeMonthYear: function()
 setTimeout(function()
 changeDisableDateColor();
 );

setTimeout is used because the jquery ui removes all the dates item and add again, so we wait until we have right date. Without setTimeout var unselectableDate = $('.ui-datepicker-unselectable a'); will give previous date.

Hope I answered the question.

Edited:

There was bug, when day or month is of single digit ie 1-9 then the date does not get matched and will not be disabled.

if(month.toString().length == 1)
 month = '0'+month.toString();


if(day.toString().length == 1)
 day = '0'+ day.toString();

Fixed the bug by adding 0 in front of day and month.
