Change Web's Work Week/First Day of Week Programmatically

Question

In Site Settings > Regional Settings it is possible to define a working week:

Is it possible to change the first day of the week with server-side code?

Answer 1

You can access working weeks information by modifying regional settings on an SPWeb By Powershell :

$web = Get-SPWeb "http://yourweb" 
$web.RegionalSettings.WorkDayStartHour = (8 * 60) #8h converted in minutes
$web.RegionalSettings.WorkDayEndHour= (20 * 60) #convert in minutes

you can access all properties of the SPWeb RegionalSettings $web.RegionalSettings

Same thing with C# code ;)
