Send reminder email one day before task due date

I have a calculated variable called SendEmailDate (=[Due Date]-1), which will be used to determnie when to send the reminder email because I want something to go out one day before the task is due.

Here is what I currently have for my workflow.

-- First step
If Status == Completed
    Stop task

-- Second step
If开发者_运维技巧 SendEmailDate == Today (how do I get this?)
    Send reminder email
Else
    Pause until SendEmailDate

I'm pretty sure that the logic above will work. But how do I get the current date in a workflow? I did find this which shows how to loop a workflow but that didn't really help me in my cause.

Thank you.

In the formula list in Sharepoint Designer, isn't there an option for "Current Date" that you can drop into your workflow?
