Hi;

Is there a way to determine if a given day in a Calendar is a weekend?
And/or can this be determined from the user's culture? Because it is
Friday/Saturday in the middle east and Saturday/Sunday in Europe/Americas,
and probably something else somewhere else.

Hi Dave,

Based on my research, there is no such a method to do that.
You may try to use the approach below to get the first day and know the
weekend should be the previous two days.

But there is also no 1-to-1 correlation between the "first day of the week"
and the weekend being the last two days in the week, either....

So I think you may try to considered your concrete scenario and do the
calculation.

This is not good. Sunday is the first day of the week here in the U.S. (I
think Monday is in Europe) so I don't think that will work.

We may have to hord-code it ourselves by locale. To that point - is it
Saturday/Sunday in PRC?

Hi Dave,

Yes you are right, in PRC , the Saturday/Sunday is the Weekend. and
Monday-Friday is the Weekdays.

If you have any other concern, please feel free to let me know.

Hello Dave,

Just a little add-ons, yes, there is no direct method in .net FCL to
determine whether a given day is weekend (according to a given Calendar).
However, you can still easily do the work by using the
System.Globalization.Calendar and its derived classes. For example:

============================
System.Globalization.Calendar calendar = new
System.Globalization.GregorianCalendar(System.Globalization.GregorianCalenda
rTypes.Localized);

Response.Write("<br/>today(Localized): " +
calendar.GetDayOfWeek(DateTime.Now));

calendar = new
System.Globalization.GregorianCalendar(System.Globalization.GregorianCalenda
rTypes.USEnglish);

Response.Write("<br/>today(USEnglish): " +
calendar.GetDayOfWeek(DateTime.Now));

calendar = new
System.Globalization.GregorianCalendar(System.Globalization.GregorianCalenda
rTypes.MiddleEastFrench);

Response.Write("<br/>today(MIDDLEEAST): " +
calendar.GetDayOfWeek(DateTime.Now));

============================

After you get the "DayOfWeek" value, you can determine whether it is
weekend.

Hope this helps.

Sincerely,

Steven Cheng
