Adding the Property
First, navigate to the ✅ All Tasks [UB] database. It can be found in a toggle at the bottom of the 🔦 Archive page.

Now, unlock the database by clicking the Locked
button at the top of the page.

Then, scroll to the left of the table view here, and click the plus icon to create a new property.

Name the property Do Date, choose Date
as your property type.
Now, open one of the database pages. Drag the Do Date property to the top, set it to Always show
.

(If you can’t see the property, click the little down arrow with XX more properties
, it’ll expand the full properties list).
The property is now created - feel free to use it however you’d like! You can also change the Date format to Relative, like it is set in the Due Date property. To achieve that, click on the property name, then Edit property
→ Time format
→ Relative
.

Updating your filters
Now that the property has been added, we can go in and modify the filters. Keep in mind that there are multiple ways to do this. For example, you could create a new few only with tasks that have a Do date, and keep all the rest with Due dates on a separate view. However, in this example, we’ll go ahead and have both days displayed in a single view.
Once you’re in that view, first click the blue Filter
button. That will reveal an X rules
button. Click that to open the full filter menu.

Now, navigate to the Due filter. Click Turn into group
.

Once your group has been created, click Add filter rule
.

And lastly, set the filter operator within the group to Or
, and then create the same filter setup as for the Due property, but this time for Do.

Your Do Date setup is ready to use! With this filter setup, tasks will show up in the Today view based on either their Do or Due date.
