need a ready calendar with recurring events (day, months)
are you using wordpress by any chance, because there are some very nice plugins available for free...
No I do not use WordPress, I need this calendar to your project
What have you attempted thus far?
I think this is the answer to your question. Free event calendar widget that's an iFrame. It syncs with 3rd party calendars and Facebook and also has all the social features built in. http://www.squaredout.com/
This is a demo of a script which announces a weekly meeting (in this case, Wednesday at noon): nextwed.htm if that helps.
