Repeating Calendar entries in Lotus Notes:

When you schedule a meeting, click on repeat, and you will see a wide variety of options. You can choose when the meeting should repeat (weekly, monthly, yearly), for how long (duration or to a specific date), and even control things like what happens on weekends (move to Friday or Monday, or don't schedule at all). You can even choose "Custom" to select specific dates if none of the available combinations of parameters accomplishes what you are looking for. The dates are also computed and displayed for you in real time on the right hand side.
