Very naice calendar. I made some minor changes like yearly recurection of events. I also translated it in Italian. If someone is interested in these changes may contact me,
I installed this application in my web-server (Apache2.2 PHP5.4). For very easy code for modification. I already almostly localize to Japanese. Works well enough except for Basic authentication (Apache included). For Basic auth prompt every time appeared, I added my own auth logic using PHP session.
