Crystal Reports Formula, regarding date.

Hi

I need to write a formula that shows that if the gift date is before 30/04/YYYY then the Date received should show up as the Gift Date, which is in the record and if it is after 30/04/YYYY then it should be 21/12/YYYY

in the Gift Date record the format is

DD/MM/YYYY 12:00AM

How do I take out the time and just keep the date. What kind of code can i write to just take out the time part of the field.
