The format of this calendar was adapted from the award winning WWW Calendar Generator V2 (http://www.intellinet.com/CoolTools/CalendarMaker/) but the source code is in Python. The CGI handling code was borrowed from Aaron Watter's book Internet Programming with Python and the calendar printing code is mine (cal2htm.cgi using a revised calendar module calend2.py).
