This Week vs Last Week

[Anonymous]

Hi,

I have a text column called 'Week Indicator' that I want to create based on date values between last week and this week.

If the date is in last week then value = 'Last Week'
If the date is in this week then value = 'This Week'

What is the best way to do this?

I can't seem to use the query Date.IsInPreviousWeek for some reasoonm in the column function..

@Anonymous,

In Power query, there is Date.IsInCurrentWeek functin that returns a logical value indicating whether the given Date/DateTime/DateTimeZone occurred during the current week, as determined by the current date and time on the system.

To check if the date is in previous week, there is no such a function to achieve this directly. You need to return the week number and previous week number, and check if the week number=previous week number. We can use Date.WeekOfYear function in Power query to get the week number.

Hi guys,

Thanks for thereplies.

Yes v-caliao-msft, you are correct there is no function to find date in current week which is pretty annoying.

That said, I turned to power query and just added a new column with those existing methods:

Date.IsInCurrentWeek

Date.IsInPreviousWeek

hi @Anonymous

Have a look at this solution which should enable you to create the columns that you need. 

You can then use the columns IsInCurrentWeek and IsInLastWeek
