When you create a plan you must select the execution date. By default, the system will select today's date, although you can change it. However, this setting is editable.
How to change the default execution date
You will be able to choose whether they are created by default: for the same day (for today) or for the following day (for tomorrow). To set this, you must do it in the following way:
Access Project Settings
Plans section
Define the default execution date from the drop-down list.
This way, every time you create a plan, it will be created for the default day you have defined.
Note: If you want Planner to always ask you for the date when creating a plan, you must activate the option Edit information when creating the plan.
How to change the date of a plan
In any case, no matter what date you have set, you can edit this information later by following the procedure below:
Access the plan
Click on the 3 dots (right of the name of your plan)
Select Plan Settings from the drop-down list
Define the Execution Date you want and Save changes to finish.
