## Week over Week Change

Hey All,

I am trying to figure out week over week change for metrics by social platforms (i.e comments on twitter, comments on facebook etc.)  What I can't wrap my head around is each post has a different day and metric associated and how I would roll that up. I included the time frame colums I have. Thanks everyone!

## Re: Week over Week Change

Hi @Philsap,

```Measure =
VAR lastWeekAmount =
CALCULATE (
SUM ( Append1[Video Views] ),
FILTER (
ALL ( 'Calendar' ),
'Calendar'[WeekNum]
= MIN ( 'Calendar'[WeekNum] ) - 1
)
)
RETURN
DIVIDE ( SUM ( Append1[Video Views] ) - lastWeekAmount, lastWeekAmount, 0 )```

## Re: Week over Week Change

Hi @Philsap,

I think you have done the most of the work. You have week numbers. You can sum up or average base on week number.

I would suggest creating a new date table in case you would use some time intelligence functions.

1. Create a date table.

```Calendar =
CALENDAR ( DATE ( 2016, 1, 1 ), DATE ( 2017, 12, 31 ) ),
"WeekNum", WEEKNUM ( [Date] )
)```

2. Add a new column to "Append1" due to the dates have time part.

`DateForRelationship = [Date].[date]`

3. Establish relationship.

Please check this file: https://1drv.ms/u/s!ArTqPk2pu-BkgROntwcC_mRlVBAU. There is a demo of visual in it.

Best Regards!

## Re: Week over Week Change

Thank you so much @v-jiascu-msft! I've been banging my head on this for a week. Just some quick notes for future people

```Calendar =
CALENDAR ( DATE ( 2016, 1, 1 ), DATE ( 2017, 12, 31 ) ),
"WeekNum", WEEKNUM ( [Date] )```

The above column add will default to Sunday as the week start date. To change to Monday as the start date, simple put ( [Date},2 )

For me, I needed it attached to my main query slicer. The solution I found was adding a column under my main table

Week1 = WEEKNUM('Append1'[Date],2)

I then changed the WoW formula accordingly to reference the main table vs the Calendar table.

## Re: Week over Week Change

I used this but the calculation is not showing the right numbers. I have my Fiscal calendar all set with the correct fiscal week number. My guess it has something to do with week numbers the same between multiple fiscal years. Anybody encountered this and have a fix?
