This is an interesting start, but not quite what I'm looking for. In this solution you have to know the first Monday for any calculation. I'm looking to take to dates and then calculate the number of mondays between them without having to know the first Monday in T-SQL, if possible.

Hey, I appreciate your feedback. I'm not saying that your solution is wrong. What I'm looking for is a formula that would be inside a stored procedure. Another stored procedure will be calling it and all this stored procedure would know would be the start date and the end date. From that, I'd like to calculate the number of Mondays between the two dates.

For this i have created a function in which you have to pass two date from to to date

and it will calculate the no.of mondays in the given two dates

Create Function Monday(@dt1 datetime,@dt2 datetime) returns int as Begin Declare @cnt int,@dt as datetime

set @cnt=0 if @dt1 < @dt2 Begin set @dt=@dt1 while @dt <= @dt2 Begin if Datepart(dw,@dt)=1 Begin set @cnt=@cnt+1 set @dt=dateadd(dd,1,@dt) End set @dt=dateadd(dd,1,@dt) End End

Amit,

Nice function - I think one small change could also speed it up - since weeks are a predictable format, when you encounter a Monday skip ahead the next 6 days - the second dateadd will then add one more day - once you find a Monday, you only need to check the Mondays....

Create Function Monday(@dt1 datetime,@dt2 datetime) returns int as Begin Declare @cnt int,@dt as datetime

set @cnt=0 if @dt1 < @dt2 Begin set @dt=@dt1 while @dt <= @dt2 Begin if Datepart(dw,@dt)=1 Begin set @cnt=@cnt+1 set @dt=dateadd(dd,6,@dt) End set @dt=dateadd(dd,1,@dt) End End
