Answer 1

check this

select datepart(Month,DateColumn) Mnth,datename(Month,DateColumn) MnthName,datepart(Year,DateColumn) Year1,((day(DateColumn)-1) / 7) + 1 week from dbo.Table

Answer 2

Try using the DatePart function as shown in the following:

select
  datepart(year,Mydate), 
  datepart(month,Mydate),
  datepart(week,Mydate)
From
  MyTable

Note: If you need to calculate the week number by ISO 8601 standards then you'll need to use datepart(iso_week,Mydate)

You could also look at the DateName function

select
  datename(month,Mydate)
From
  MyTable

Answer 3

Here is another way. Use SQL Servers YEAR() and MONTH() functions. For week, I use datepart(week,Mydate) as noted by @DMK.

SELECT YEAR(MyDate), MONTH(MyDate), DATEPART(WEEK,Mydate) From YourTable
