You can manually add 3 dates for an To-do
- Due
- Started
- Completed
Due date is displayed in various places including
- Calculating how much time is left to complete the To-do
- Displayed in the OKR / To-do views along side the OKR period
- Extending the state timeline to show graphically the time remaining

The Started and Completed dates can be used override the dates that the app calculates from from the status updates.
