Is there a way to repeat a task on a weekly or Monthly basis. I know I can repeat daily, but I have certain tasks which only occur on a weekly or monthly basis.
Yes, you can set many different recurring due dates. For example, you can type "ev Mon" (or "every Monday") or "every 16" (for a task due on every 16th of each month) or even "every 3 days starting tomorrow" within the due date field.

Ok, how can I make a task that is repeating every 5 weeks after previous task was finished?
I need to visit my doctor every 5 weeks, but it is not very strict. If i cannot visit him exactly after 5 weeks, I can go after 4, 6 or even 7 weeks and it would be fine. The thing I would like to have is to get task automatically recreated in 5 weeks period after I tap current one as done.
@Maciej Musial: put "after 5 weeks" instead of "every 5 weeks".
