Using Powershell how do you get the weekday number?

Using a Powershell date object how do you get the day number of the week, 0 to 6 where 0 would be Sunday and 6 would be Saturday. I know that I can get the day name with the code below but how do I get the number as there is no DayNumberOfWeek or equivalent property?

(Get-Date).DayOfWeek

I suppose I could use the day name from the code above in a switch statement to convert it to a number but that doesn't seem to be very eloquent.

On Friday the 17th:

(get-date).DayOfWeek.value__

Returns 5

(Get-Date).DayOfWeek

Returns Friday

(Get-Date).Day

Returns 17

Well, the DayOfWeek property of a DateTime is not a string but rather a DayOfWeek enum, so the shortest answer is probably

[Int] (Get-Date).DayOfWeek  # returns 0 through 6 for current day of week

Or

[Int] [DayOfWeek] "Wednesday"  # returns 3

like this:

( get-date ).DayOfWeek.value__

I suggest for the future to investigate what properties an object in this way:

( get-date ).DayOfWeek | gm -f # gm is an alias for get-member
