You don't really need to convert the date, you can change a string but a date is a date.
You can change with the format value if you start with a date
dim dtDate as date, strDate as string
dt=now()
strDate=format(dt,"YYYYMMDD")
or change the string to a string
strDate =format(dt, "DDD MMM, DD YYYY")
strdate=format(cdate(strdate),"YYYYMMDD")
