Is there a way to set the first DayOfWeek as Monday = 0 not Sunday? (int)dateList[0].DayOfWeek == 0) // 0 = Sunday You would need to create a custom culture, and specify the initial DayOfWeek as Monday. An instance of your custom culture would need to be set to whatever context is normally used to access culture information (i.e. Thread.CurrentCulture ). The following article should get you started on creating a custom culture: How to: Create Custom Cultures EDIT: I just reread your question, and I noticed something. You can not change the DayOfWeek property...that is simply an enumeration

This question already has an answer here: Android: how to get the current day of the week (Monday, etc…) in the user's language? 9 answers i tried to get a string with the name of the actual weekday this way: Calendar c = Calendar.getInstance(); int dayOfWeek = c.get(Calendar.DAY_OF_WEEK); if (c.get(Calendar.MONDAY) == dayOfWeek) weekDay = "monday"; else if (c.get(Calendar.TUESDAY) == dayOfWeek) weekDay = "tuesday"; else if (c.get(Calendar.WEDNESDAY) == dayOfWeek) weekDay = "wednesday"; else if (c.get(Calendar.THURSDAY) == dayOfWeek) weekDay = "thursday"; else if (c.get(Calendar.FRIDAY) ==

How do I localize a DayOfWeek other than today? The following works just fine for the current day: DateTime.Now.ToString("dddd", new CultureInfo("it-IT")); But how can I localize all days of the week?? Edit: A possible (and probably very, very wrong) solution I came up with could be to create DateTime values for an entire week, and then use date.ToString("dddd", new CultureInfo("it-IT")); on them, but that just seems wrong on so many levels. How about DateTimeFormatInfo.CurrentInfo.GetDayName( dayOfWeek ) or DateTimeFormatInfo.CurrentInfo.GetAbbreviatedDayName( dayOfWeek ) Simply takes a

I am wondering if there is a way to average daily data into weekly data. The dataframe that I call CADaily looks like this: > CADaily[1:10, ] Climate_Division Date Rain 885 1 1948-07-01 0.8750000 892 1 1948-07-02 2.9166667 894 1 1948-07-03 0.7916667 895 1 1948-07-04 0.4305556 898 1 1948-07-05 0.8262061 901 1 1948-07-06 0.5972222 904 1 1948-07-17 0.04166667 905 1 1948-07-18 0.08333333 907 1 1948-07-20 0.04166667 909 1 1948-07-22 0.12500000 910 1 1948-07-21 NA My objective is similar to the aggregate function to find the average of the daily rain into weekly rain values base on the Date (of

In VB6 code, I have the following: dim I as Long I = Weekday(Now, vbFriday) I want the equivalent in C#. Can any one help? public static int Weekday(DateTime dt, DayOfWeek startOfWeek) { return (dt.DayOfWeek - startOfWeek + 7) % 7; } This can be called using: DateTime dt = DateTime.Now; Console.WriteLine(Weekday(dt, DayOfWeek.Friday)); The above outputs: 4 as Tuesday is 4 days after Friday. You mean the DateTime.DayOfWeek property? DayOfWeek dow = DateTime.Now.DayOfWeek; Yes, Each DateTime value has a built in property called DayOfWeek that returns a enumeration of the same name... DayOfWeek

Given 03/09/1982 how can we say it is which week day. In this case it will be Tue . Is it possible to get in a single query?
