This is a web event calendar developed using PHP and powered by MySQL. The calendar is viewed initially in month format with a separate page detailing the events of each day as they are clicked on. The calendar is customizable within a single file; allowing changes to the title, color choices, starting day of the week, language, time format(24hr/12hr), and time zone display.

It will be good to see extension for this calender.
