[RESOLVED] WeekdayName -> Date.DayOfWeek vs Weekday() different

Dt = 7/16/2013 Tuesday....

Dim DN As String = WeekdayName(Weekday(dT))
DN = Tuesday

Dim DN As String = WeekdayName(dT.DayOfWeek)
DN=Monday

Any clue why?

dT.DayOfWeek should already return the weekday name, but since you are using it as a parameter it passes the integer value to WeekdayName, which has a different set of indexes than DayOfWeek. DayOfWeek integer values are 0 - 6, which represent the days of the week, while WeekdayName is 0 - 7, with 0 being a flag for the system first day of the week.

edit: Sorry I read it wrong, it does return an integer, but the indexes are still different. The first example you listed should be the correct way

ahhh!!! i missed that!!! DayOfWeek is 0-6

bingo!

thank you! was driving me nuts! lol

You do not need to use WeekdayName.

Code:

---

        Dim DN As String = Dt.DayOfWeek.ToString
