Fullcalendar v5 first day in dayGridMonth not working

I want set current date visible first. But it isn't working.
Documentation https://fullcalendar.io/docs/view-object
var calendarAll = new FullCalendar.Calendar(calendarEl, {
headerToolbar: {
left: 'today',
center: 'prev,title,next',
right: 'month30,dayGridMonth,timeGridWeek'
},
initialView: 'month30',
views: {
month30: {
type: 'dayGridMonth',
buttonText: 'month30',
//activeStart: new Date(), //Not working
visibleRange: function(currentDate) {
var startDate = new Date(currentDate.valueOf());
var endDate = new Date(currentDate.valueOf());
startDate.setDate(startDate.getDate() - 1);
endDate.setDate(endDate.getDate() + 29);
return { start: startDate, end: endDate };
}
}
},
});
How can I fix it? Fullcalendar v5, without jquery.

The "month" view provided by fullCalendar does not have this flexibility - it always starts at the beginning of the month, like a traditional paper calendar.
IMHO it would be confusing to many users if it appeared differently.
Other types of view are more flexible - they will respond to the visibleRange setting if you do not specify the time range in the view name, such as if you specify timeGrid rather than timeGridWeek for example.

Change type: 'dayGridMonth' to type: 'dayGrid'

FullCalendar Resource View - Week View w/Previous 3 Days Shown

I have provided a TimelineResourceView below as a reference as an example current setup.
Example: If Week View Sun-Sat Then anytime navigating forward/backward, always show week view with previous 3 days from week range. Then anytime navigating forward/backward, always show week view with previous 3 days from week range.
FullCalendar Example Timeline ResourceWeekView

I tried many different things from docs such as "visiblerange" and forcing dates with no success.
https://fullcalendar.io/docs/visibleRange
[Sun Oct 27 – Sat Nov 2] but they want to see [Thurs Oct 24 – Sat Nov 2] to show the previous 3 days.
calendar.setOption('visibleRange', {
start: '2019-10-24',
end: '2019-11-02'
});

Persistence paid off. I achieved a custom view using VisibleRange and with Moment javascript library. I answer this myself knowing this could be helpful for others formulating a custom view. Mine was focused on the timelineResourceViewm but should be able to apply to the other day/week views etc.
See CodePen:
Working Example Week View with Previewing Last 3 days (10 Day View)
document.addEventListener('DOMContentLoaded', function() {
var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
plugins: [ 'interaction', 'resourceTimeline' ],
timeZone: 'UTC',
header: {
left: 'today',
center: 'title',
right: 'resourceTimeline'
},
defaultView: 'resourceTimeline',
views: {
resourceTimeline: {
visibleRange: function (currentDate) {
// Generate a new date for manipulating in the next step
var startDate = new Date(moment(currentDate).startOf('week').format("YYYY-MM-DD"));
var endDate = new Date(moment(currentDate).startOf('week').format("YYYY-MM-DD"));
// Adjust the start & end dates, respectively
//10 Day WeekView PREV Thurs -> Sun-Sat
startDate.setDate(startDate.getDate() - 3); //Set Past (show back Thur)
endDate.setDate(endDate.getDate() + 7); // Set Future (standard week from Sun)
return { start: startDate, end: endDate };
}
}
},
slotLabelFormat: [{ weekday: 'short', month: 'numeric', day: 'numeric', omitCommas: true }],
slotLabelInterval: { days: 1 },
editable: true,
resourceLabelText: 'Rooms',
resources: 'https://fullcalendar.io/demo-resources.json?with-nesting&with-colors',
events: 'https://fullcalendar.io/demo-events.json?single-day&for-resource-timeline'
});
calendar.render();
document.getElementById('prev').addEventListener('click', function() {
calendar.incrementDate({ days: -7 });
});
document.getElementById('next').addEventListener('click', function() {
calendar.incrementDate({ days: 7 });
});
});

For anyone else coming across this. v5 now supports this as visible range.

How to disable range of time in Kendo datetime picker javascript

How to rage of time in kendo datetime picker exapmle:
disable time range 03.01.2019 10:00am - 03.01.2019 10:30am
$("#datetimepicker").kendoDateTimePicker({
value: new Date(),
dateInput: true,
format: "MM/dd/yyyy HH:mm",
interval: 5,
timeFormat: "HH:mm",
min: new Date(yyyy, mm - 1, dd + 1, HH, MM, 0),
disableDates:[]
});

you might consider using DatePicker instead of DateTimePicker
$(document).ready(function() {
// create DatePicker from input HTML element
$("#datepicker").kendoDatePicker({
value: new Date(),
dateInput: true,
format: "MM/dd/yyyy"
});
});
Hope it helps!

Javascript flipclock countdown generates incorrect date format

I'm working on a website were I'd like to use a countdown to a special event. I've now installed the flipclock.js script and it's up and working. But, it generates incorrect date formats, like attached image:
As you can see, the days, minutes and seconds are working as expected, but the "hour" is showing 93. I've used the following code to implement the flipclock.js:
var date = new Date(2018, 11, 8, 12, 0, 0);
var now = new Date();
var diff = (date.getTime() - now.getTime()) / 1000;
console.log(date);
var clock;
clock = $('.clock').FlipClock({
clockFace: 'DailyCounter',
autoStart: false,
callbacks: {
stop: function() {
$('.message').html('The clock has stopped!')
}
}
});
clock.setTime(diff);
clock.setCountdown(true);
clock.start();
Does anyone know why it's doing like this? I haven't changed anything in the

Just in case someone is still looking for the solution... Here's the content of the link that NoLifeKing refers to in the comments section.
It looks like this issue occurs if you do the following:
clock = $('.clock').FlipClock({
'autoStart': false,
'clockFace': 'DailyCounter',
'countdown': true,
});
clock.setTime(diff);
clock.start();
as opposed to what is done below:
clock = $('.clock').FlipClock(diff, {
'autoStart': true,
'clockFace': 'DailyCounter',
'countdown': true,
});

how to disable date before today in datepicker

I want to disable dates before today.(i.e. say today's date is 04Oct17 and I would like all the dates before this disabled but still enabling user to go to previous months, years, etc.)
$(document).ready(function () {
var date_input = $('input[name="date"]'); //our date input has the name "date"
var container = $('.bootstrap-iso form').length > 0 ? $('.bootstrap-iso form').parent() : "body";
var options = {
format: 'mm/dd/yyyy',
container: container,
todayHighlight: true,
autoclose: true,
};
date_input.datepicker(options);
})

In your datepicker options add minDate
var dateToday = new Date(); // Today's Date.
var options = {
format: 'mm/dd/yyyy',
container: container,
todayHighlight: true,
autoclose: true,
minDate:dateToday // <--- this will disable all date less then dateToday
};
date_input.datepicker(options);
