Find First and Last Day Of Each Month

The first day of each month is always 1. However if you interested to find the First and Last Date of each month using a T-Sql Query, here it is:

-- Return First and Last Date of a Month
DECLARE @Month smallint
SET @Month = 1

SELECT DAY(DATEADD(Month, DATEDIFF(Month, -1, getdate()) - 2, -1) + 1) as FirstDayofMonth,
DAY(DATEADD(Month, DATEDIFF(Month,0,getdate())+@Month, -1)) as LastDayOfMonth

If you wish to find out the Lastday of the previous month, just set @Month to 0.

Note: The value for @Month depends on the current month you are in. So if this month is September, the value of @Month is 1. Similarly for Oct(2), Nov(3), Dec(4), Jan(5), Feb(6) and so on.

    Hi,

    The query works fine. The value for @Month depends on the current month you are in. So if this month is September, the value of @Month is 1. Similarly for Oct(2), Nov(3), Dec(4), Jan(5), Feb(6) and so on..

    I have added a note to avoid confusion. Apologies if that wasn't clear earlier.
