Answer 1

Try to run the following query, it will give you everything you want :)

Declare @a date =dateadd(mm, Datediff(mm,0,getdate()),0)
Print('First day of Current Month:')
Print(@a)
Print('')
set @a = dateadd(mm, Datediff(mm,0,getdate())+1,-1)
Print('Last day of Current Month:')
Print(@a)
Print('')

Print('First day of Last Month:')
set @a = dateadd(mm, Datediff(mm,0,getdate())-1,0)
Print(@a)
Print('')

Print('Last day of Last Month:') 
set @a = dateadd(mm, Datediff(mm,0,getdate()),-1)
Print(@a)
Print('')


Print('First day of Current Week:')
set @a = dateadd(ww, Datediff(ww,0,getdate()),0)
Print(@a)
Print('')

Print('Last day of Current Week:')
set @a = dateadd(ww, Datediff(ww,0,getdate())+1,-1)
Print(@a)
Print('')

Print('First day of Last Week:')
set @a =  dateadd(ww, Datediff(ww,0,getdate())-1,0)
Print(@a)
Print('')

Print('Last day of Last Week:')
set @a =  dateadd(ww, Datediff(ww,0,getdate()),-1)
Print(@a)
