This does the same as my last post. It just has the functions calls for SundaysInMonth nested.

select

[Year]= year(a.DT),

[Month] = month(a.DT),

SundaysInMonth =

(datediff(dd,

dateadd(dd,((datediff(dd,-53684,dateadd(mm,datediff(mm,0,a.DT),0)+6)/7)*7),-53684),

dateadd(dd,((datediff(dd,-53684,dateadd(mm,datediff(mm,-1,a.DT),-1))/7)*7),-53684)

)/7)+1

from

( -- Test dates, all months for 2008

select...

This shows a different method that only requires a single select statement.

select

[Year]= year(FirstSunday),

[Month] = month(FirstSunday),

SundaysInMonth = (datediff(dd,FirstSunday,LastSunday)/7)+1

from

(

select

*,

FirstSunday =

-- First Sunday of the Month

dateadd(dd,((datediff(dd,-53684,aa.Day7)/7)*7),-53684),

LastSunday =

-- Last Sunday of the Month

dateadd(dd,((datediff(dd,-53684,aa.EOM)/7)*7),-53684)

from
