title: mydatepicker disableSince option in case of date of birth validation
body: <p>I am using mydatepicker <a href="https://www.npmjs.com/package/mydatepicker" rel="nofollow noreferrer">https://www.npmjs.com/package/mydatepicker</a> for my calender field . The field is Date of Birth field. As its logically clear , i need to disable the future dates by getting the current date . I have gone through the doc . It has disableSince option with year, month and day parameters. I am unsure how to pass current date + 1 ( +1 because i need the current date to be in enabled state, only the future dates should be disabled ) to disableSince option . </p>
  
  <pre><code> &lt;my-date-picker name="DOB" class="form-control calander required mousechange customCalender" [options]="myDatePickerOptions"
                        formControlName="DOB"   placeholder="DD / MM / YYYY" &gt;&lt;/my-date-picker&gt;
  
  
  public myDatePickerOptions: IMyDpOptions = {
      // other options...
      dateFormat: 'dd / mmm / yyyy',
      disableSince: {year: 2018, month: 6, day: 1}
  };
  </code></pre>
