Custom Frequency

Just because it is called daily task, does not mean it should be done every day.

You can specify custom freqency for event on your task list to occur every 2 or 3 days, on specific days of week or even on some days of a month. Apart from that, you can always choose dates range for your task, so it ends after some period of time.
