first, you need to calculate the date for the notification.
For this, you can use an arithmetic expression with DateAdd()
and store the result in a DateTime variable.
Next, you can create a time delay step which delays until the date from your variable is reached.
Keep in mind that time delay needs a date with time. When writing a date without time to a date variable, the time is automatically set to 12 pm UTC.
You might need to use a second DateAdd() to set the time to a different value.
Once the DateTime is reached, your task is triggered.
Hope this helps.
