The Modify Date activity in UiPath is used to update a date value using modifications including adding or subtracting days and finding the first or last day of the week, month, or year
Here is an example of how to use the Modify Date activity to add 7 days to a date:
Drag and drop the Modify Date activity onto your workflow.
In the Properties panel, set the DateToModify property to the date you want to modify.
Set the DaysToAdd property to 7.
Set the Result property to a variable that will store the modified date.
You can also use the Add Days method of the DateTime object to add or subtract days from a date.
