Schedule (event) call and roll over event on calendar?

Schedule (event) call and roll over event on calendar?

This will be the make of break for my using Zoho or moving on.

The following is a staple for those doing sales with many calls.  I must be missing the obvious?
  • If a call is completed with a lead/contact and I need to call them in 7 weeks at 9:10 am, how do I schedule this event?
  • How do I have these event roll over on the calendar?
  • How do I schedule a 5 minute event (not a 30 min event)?

Thanks!
