Build my schedule webpage in html css and js, and php

I have a page that is be created in HTML, css and javascript. it should be functional too. You have 6 hours to complete the project as I have major deadline. I have main code for basic page ui, but you will be building the inner page with the calendars and calendar interface on the right side. I have main ui with nav and that's it. you should be able to create the rest of this, features - adding a scheduled time and posting it on main big calendar. by clicking the + button, this would display on the calendar UI on the right. - editing an event and save it. An event would include a event title, calendar to select the date and time and then user to meet with, this can be typed in. (later can be from a db) - when you add time on the big calendar, that would just create a list of available time we would post in the json of what time is available in 30 mins increments for example - you post a new time range on Wednesday from 7am to 9am, the visual time would show on the big calendar and in the json on the console you should be able to see the available time on that do to be 7:00, 730, 800, 830. Complete the UI, and the functionality within the time frame.
