hi,
have you tried to hack something with week, month and weekofyear ?
there is an interesting url at
http://dev.mysql.com/doc/mysql/en/date-and-time-functions.html
be aware that the week begins on sunday.
mysql> select weekofyear('2005-01-02');
+--------------------------+
| weekofyear('2005-01-02') |
+--------------------------+
| 53 |
+--------------------------+
1 row in set (0.00 sec)
mysql> select weekofyear('2005-01-03');
+--------------------------+
| weekofyear('2005-01-03') |
+--------------------------+
| 1 |
+--------------------------+
you can then construct a week-based calendar for the events.
hope that helps.
