This Week vs Last Week

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..

    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.
