DateAdd only Adds.

Slightly cryptic title but I was expecting the DateAdd function to subtract if a negative is passed in but due to the looping use the number of days to add it bails out straight away.

Hello,
Yes. That's how it works at the moment. Thanks for the issue. I'll include this task to the long list of fixes I work on :)
