Column with -1 dates

[MintuBaruah]

Hello All,

I wanted to create a column in the Power query to show previous dates from the existing column. Please refer to the expected results table:

Date		Previous Day-Date
23/01/2023		22/01/2023
22/01/2023		21/01/2023
01/12/2022		30/11/2022

In the above example: The Date is the column I have and the Previous Day-Date is the column that I want to show.

Please help resolve this problem.

Thank you.

Hi @MintuBaruah .
You can simply use PREVIOUSDAY() function.

For example :-Measure 2 = PREVIOUSDAY(Orders[Order Date])
