HTML/JS/CSS/PHP/MySQL Calendar

This is a very simple project from any experienced web developer, all what I need is a single php file which will be used as a big calendar (see the attached image), where: 1- This calendar displays the days of a certain month of a certain year (i.e. January 2015) 2- The user should be able to move backward or forward to any other month in any other year 3- The events to be displayed on the calendar should be displayed using two different colors (we should be able to change these colors later either from the code or from the DB), one color to be used for national events and one color to be used for international events 4- When the user clicks on any colored box inside the calendar a lightbox will appear to show more about this specific event 5- The data to be shown in the calendar itself would be the event name only while the data to be displayed in the lightbox should be (event name, event date and time, event category national or international, event description and a URL for the event website) 6- All such data should be retrieved from a MySQL DB so the calendar itself should only be a placeholder for events that can be added,deleted or changed in the MySQL DB 7- The width of the php/html file that will hold the calendar should be 950 px where the width of the calendar itself should be at least 850 - 900 px Good luck and please note that I will need this in a maximum of 3 days Thank
