WeekdayName

Hello, any advice appreciated please.

I have as a column heading the expression =WeekdayName(weekday(fields!date.value))

This returns the day of the week, however, it is returning a day of the week one day in advance, eg when I put Monday's dates in the parameter it shows as 'Tuesday' in the report.

My question is can the above expression be tweaked to show the WeekdayName one day before, eg =WeekdayName(weekday(fields!date.value -1)) ? I tried this but got an error.

Thanks.
