Dates and Times

When you have tasks to complete by a deadline, OmniFocus can help weave actions and projects into your day.

By design, the items you collect in OmniFocus aren’t the same sort of thing as events or agenda items you’d list on a calendar. You’d generally use a calendar for anything that takes place at a specific time: meetings, dentist appointments, and dinner reservations would do best in your calendar because you can’t act on them until that moment.

Setting Defer and Due Dates

Actions and projects can have due dates and “defer until” dates with a less specific notion of time constraint than items in your calendar. The defer until date is the date when an action or project becomes available; until that date arrives, the item remains grayed out. The due date is the date when an action or project needs to be completed.

For example, to make progress on your Colonize Mars project, you need to know when Mars is in opposition so you can schedule a date during the launch window. A quick online search shows that the next window is from January 2016 to April 2016, so you decide to launch your spacecraft on January 6 to commemorate your birthday. To keep track of this, you might create a Launch Window action with a defer until date of January 1, 2016 and a due date of April 31, 2016.

While you’re at it, you also create a Launch Spacecraft action with a defer until date of January 6, 2016 and a due date of April 31, 2016. So why not just a due date for Launch Mission? Well, because weather conditions for a launch could be bad that day, or there could be some sort of mechanical failure that delays the launch. Regardless, that is the day you know you’d like to launch the rocket, and if that date passes, OmniFocus reminds you until you’re past the due date and off to explore the Red Planet.

Items that have not reached their defer until date are not considered available so they won’t clutter your view until you can work on them. To see all of the actions in your Colonize Mars project, choose Remaining in view options (All includes completed and dropped items). Actions with a future defer date are in gray. When the defer date arrives, the action’s text appears in black to let you know it is available and the clock is ticking.

When due dates are approaching, OmniFocus considers actions and projects to be Due Soon and represents them as such by changing their color from black to amber and adding them to the Forecast (see Forecast View). By default, actions become “due soon” two days before the specified due date. To change this, go to the OmniFocus ▸ Preferences ▸ Dates & Times tab and choose a different value for “Due Soon”.

Also in the Dates & Times section of preferences, you can choose which time of day to use for when you enter a due date with no time. By default it is 5:00 PM; you could for instance enter 11:59 PM to make new items due at the very end of the day, or 9:00 AM to make new items due at the beginning of the workday.

Note
New in OmniFocus 2, you can also (in OmniFocus > Preferences > Dates & Times) customize the default time for actions and projects with defer dates to become available. The starting default is 12:00 AM, but you could change it to a time that’s better suited to when you habitually check OmniFocus for newly available actions, for example.

Defer and due dates can be entered either in the main outline or in the inspector.

Actions that have reached their due date are styled in red. This serves as a warning to you that you should either get that task done, or reschedule its due date. In the case of the Mars mission, if you miss the launch window, you’ll have to wait another 24 months for your next opportunity.

Supported Date Formats

You can be pretty creative with the way you enter dates; OmniFocus is rather smart about guessing what you mean. For example:

Note
In cases where due dates vary between actions and the projects that contain them (such as an action being part of a group that’s nested within a project, all with different due dates), the soonest due date is considered the effective due date for all items that are its children in the hierarchy.

For example, if you have a project due on the 4th of the month and actions within that are due on the 2nd and 3rd, but circumstances change and you need to complete the project on the 1st, the actions also become due on the 1st.

Likewise, when defer dates vary between projects and the actions and groups within them, child items will inherit defer dates of their parents if they are later than the child’s defer date.

For example, if your Launch Sequence actions are part of your Mars Expedition project but you miss the first launch window and have to reschedule, deferring the entire project to a later date will cause the Launch Sequence actions to also be deferred (they would have otherwise become available with no actual launch imminent).

Repeating Items

Some tasks occur on a regular basis. Instead of creating a new item every time you need to take out the recycling, you can set that task up so that you’re reminded every Thursday night to put the recycling bins by the road for pickup Friday morning. Repeating actions can occur regularly—every few hours, days, weeks, or months—based on when the item was first scheduled, or rescheduled to be deferred until (or be due again) based on a set time after you mark it completed.

To set an item up to repeat:

For example:

When you mark a repeating item as complete, the next instance of it is created with its start and due dates pushed forward as indicated by the repeat interval. If you want an item to stop repeating, just turn off the Repeat setting in the inspector.
