Recently I have recieved email from Vivek Jamwal, which contains many useful SQL Server Date functions.
—-Today
SELECT GETDATE() ‘Today’

SELECT DATEADD(d,-1,GETDATE()) ‘Yesterday’
—-First Day of Current Week
SELECT DATEADD(wk,DATEDIFF(wk,0,GETDATE()),0) ‘First Day of Current Week’
—-Last Day of Current Week
SELECT DATEADD(wk,DATEDIFF(wk,0,GETDATE()),6) ‘Last Day of Current Week’
—-First Day of Last Week
SELECT DATEADD(wk,DATEDIFF(wk,7,GETDATE()),0) ‘First Day of Last Week’
—-Last Day of Last Week
SELECT DATEADD(wk,DATEDIFF(wk,7,GETDATE()),6) ‘Last Day of Last Week’
—-First Day of Current Month
SELECT DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0) ‘First Day of Current Month’
—-Last Day of Current Month
SELECT DATEADD(ms,- 3,DATEADD(mm,0,DATEADD(mm,DATEDIFF(mm,0,GETDATE())+1,0))) ‘Last Day of Current Month’
—-First Day of Last Month
SELECT DATEADD(mm,-1,DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0)) ‘First Day of Last Month’
—-Last Day of Last Month
SELECT DATEADD(ms,-3,DATEADD(mm,0,DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0))) ‘Last Day of Last Month’
—-First Day of Current Year
SELECT DATEADD(yy,DATEDIFF(yy,0,GETDATE()),0) ‘First Day of Current Year’
—-Last Day of Current Year
SELECT DATEADD(ms,-3,DATEADD(yy,0,DATEADD(yy,DATEDIFF(yy,0,GETDATE())+1,0))) ‘Last Day of Current Year’
—-First Day of Last Year
SELECT DATEADD(yy,-1,DATEADD(yy,DATEDIFF(yy,0,GETDATE()),0)) ‘First Day of Last Year’
—-Last Day of Last Year
SELECT DATEADD(ms,-3,DATEADD(yy,0,DATEADD(yy,DATEDIFF(yy,0,GETDATE()),0))) ‘Last Day of Last Year’

Hi,
The above informations are really very fantastic..
May i know the how to down load sqlserver 2008 book.
Great info indeed (and your blog in general is full of ressources).
For some reporting, I need the first and last days of previous month (those I got from your useful dateTime functions) but also the first and last days of 2 months ago as well as the first and last days of 3 months… what ever is the day of today (getdate()). Any hint?
This collection will be useful for everybody, wonderful
Hey.., information was sufficient enough…, thanks and good bye
When it comes to processing dates, one thing I failed to see online is the calculation for Retail Calendar. I’m in the Retail industry and calendar is different from the Gregorian calendar. Any clue in developing a Retail Calendar other then creating a custom calendar table?
Thanks,
Chris
what if you want results from a specific date? for example, the 3rd of every month?
Great Information .Thank You
it s most usefull for developer
