The task for this project is to generate an ICAL compliant feed using data in Google spreadsheet.

The data in the spreadsheet represents the whole day events of birthdays and anniversaries. These are stored in column such as:
first name, last name, birthday, anniversary, spouse, notes, location

Google spreadsheets can generate CSV, XLS, and RSS feeds. Thus it should be easy for you to use an existing PHP class to parse one of these feed into an array and output an ICAL feed from this array.
