Rounding the date or setting day to the 1st of month

[cunner26]

For this report employees become eligible for our plan the 1st of the month following three months of service.

I currently have the following formula

Dateadd ("m",4,{eepaystatus.orighiredate})

This formula has allowed me to add 4 months to the original hire date of the employee but I am unable to either round the date down to the first of the month or set the date to the 1st.

Can you please help me with this,

DateVar HirePlus4 := Dateadd ("m",4,{eepaystatus.orighiredate});
Date(Year(HirePlus4),Month(HirePlus4),1)
