How can we make all the past dates in the calendar unselectable?

I had a html5 calender of type="datetime". I want the past dates to make unselectable.
<input class="form-control" type="datetime" date-time auto-close="true" view="date"
datepicker-options="dateOptions" min-view="date" maxlength="10" format="dd/MM/yyyy"
ng-model="$ctrl.DateInput" required="true">
All the dates inside the rectangle should be in disable state.
Can someone help me?

With Javascript, you can set the min attribute of the date control. You can also set this from your ViewModal.
var today = new Date().toISOString().split('T')[0];
document.getElementsByName("date-control")[0].setAttribute('min', today);
<input name="date-control" type="date">

Try using new Date(from_date) to see if the variable contains a valid date
This will also convert the variable type into Date type if the variable contains a valid date as well

From date , To date validation in angular js

This is my code
<tr ng-show="option == 'Yearly' || option == 'Date'">
<td>
<label>From:</label>
</td>
<td>
<input type="date" ng-model="fromdate" id="fromdate" date-picker />
</td>
<td>
<label>To:</label>
</td>
<td>
<input type="date" ng-model="todate" date-picker />
</td>
</tr>
I have a jquery date picker for fromdate and todate, I need to disable all the dates in the end date which is lesser than the from date.....

I have used https://github.com/Eonasdan/bootstrap-datetimepicker
previously and minDate and maxDate options can probably be helpful for your use case, if you want to look at another plugin.
Sample usage to set maxDate, minDate:
html:
<div class="container">
<div class="row">
<div class='col-sm-6'>
<div class="form-group">
<div class='input-group date' id='datetimepicker1'>
<input type='text' class="form-control" />
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span>
</div>
</div>
</div>
</div>
</div>
js:
$('#datetimepicker1').datetimepicker({
maxDate: new Date("6/8/2016"),
minDate: new Date("6/2/2016")
});
Working Plunker
Note: This plugin has dependency on bootstrap, jquery, and momentjs
Edit:
There is also a angular wrapper directive over this: https://github.com/diosney/angular-bootstrap-datetimepicker-directive

If you are just wanting to set a specific min date like todays date you can put that in as a setting.
https://docs.angularjs.org/api/ng/input/input%5Bdate%5D
If you have an easy way of setting your min date to be todays day you can just use a variable as such min="{{minDate | date:'yyyy-MM-dd'}}"). Note that min will also add native HTML5 constraint validation.
In theory this doesn't require a controller but just a app setup config for $scope.minDate, all that is going to do is note that your date is not correct next to the field with whatever validation you have set, field and form validation is a whole different animal then what you are asking but I would read https://docs.angularjs.org/guide/forms on it.
In the long run I wouldn't use jquery date picker and use a native directive like https://angular-ui.github.io/bootstrap/ Date picker or Angular Material https://material.angularjs.org/latest/demo/datepicker

How fill up the datepicker form with string date?

From database I get data in format like (let's suppose it's a string)
1974-07-05
How I need to pass the date in form with datepicker and make the date active there, so how can I do it?
<td>
<script src="javascript/datepicker.js"></script>
<input id="datepicker" type="text" name="dob" value="${person.bdate}">
</td>
and ${person.bdate} is a string date

This is not an answer, just an observation.
You have requested a pure javascript solution, but you are using a plugin. Why not use jQuery and jQueryUI's datepicker plugin. Look how easy the code would be:
jsFiddle Demo
HTML:
<input id="datepicker" type="text" name="dob" value="">
jQuery:
var dd = '1974-07-05';
$('#datepicker').val(dd);
$('#datepicker').datepicker({
dateFormat: 'yy-mm-dd'
});

angular-ui bootstrap datepicker (how to disable only today button on popup)

I have 2 dates : StartDate and EndDate using angular-ui-bootstrap datepicker
When I choose a startDate (greater than today date) I set the min-date of EndDate datepicker at the startDate. So all dates <= startDate are disabled.
But the Today button in popup of EnDate can set today date which is not conform business rule.
Is there a way to disable the the Today button without disabling all the button-bar?

Sample HTMl for that:
ng-model , ng-change and min-date
<input type="text" uib-datepicker-popup="dd/MM/yyyy" ng-model="personForm.StartDate" name="startDate" ng-change="myStartDateChange()" />
<input type="text" uib-datepicker-popup="dd/MM/yyyy" min-date="endmindate" ng-model="personForm.EndDate" name="endDate" />
add function in your controller:
$scope.myStartDateChange = function () {
$scope.endmindate= $scope.personForm.StartDate;
}

you should update ui-bootstrap version to 0.14.0 or laster.
it could be fix this bug.
