Rounding Calculations with dates

[Zenobia]

LengthDaysOverDue: Now()-[DueDate]

Hello I'm trying to round this up to full numbers in my query however i cannot get it work,

Can any one shed any light on how to round this calculation to whole numbers?

Thank you

Hopefully you found the DateDiff function.
Or perhaps you found to use Date() instead of Now().
