SQL SERVER: Pass Month and Year value and get First, Last and Total Days in that month

Introduction: In this article I am going to share how to find first and last day of the month and also count total number of days in the month from the month and year value.

In previous articles i explained How to Remove duplicate records from table and Get second, third, fourth or nth highest/maximum salary of employee and Full outer join in sql server with example and Get day, month and year from current or any date and Get first, last date and total number of days in month

Description: While working on Asp.Net project with Sql Sever as a backend it was required to pass month value (e.g. 3) and year value (e.g. 2016) and get the first and last date and total days in that month. Here I have mentioned the query to get the desired result.

Implementation: Let’s write sample query for demonstration purpose:

DECLARE @Month INT=3, @Year INT=2016, @FirstDate DATE,@LastDate DATE, @TotalDays INT

SET @LastDate=(SELECT DATEADD(DAY,-1,DATEADD(MONTH,@Month,DATEADD(YEAR,@Year-1900,0))))

SET @FirstDate=(SELECT DATEADD(MONTH,@Month-1,DATEADD(YEAR,@Year-1900,0)))

SET @TotalDays=(DATEDIFF(D,@FirstDate,@LastDate))+1

SELECT @FirstDate [First Date of Month] ,@LastDate [Last Date of Month], @TotalDays [Total Days in Month]

Result:

First Day of Month	Last Day of Month	Total Days in Month
2016-03-01	2016-03-31	31
