Azure logical app get first date of month - azure

Question

I have an Azure Logical app, I want to get the first date of the month two days ago.
For example:
1. If today is '2022-08-01' then two days ago was '2022-07-29', I want to get '2022-07-01' as result
2. If today is '2022-08-02' then two days ago was '2022-07-31', I want to get '2022-07-01' as result
3. If today is '2022-08-03' then two days ago was '2022-08-01', I want to get '2022-08-01' as result
I already know I can get date for two days ago using "#addDays(utcNow(), -2, 'yyyy-MM-dd')" but I basically need first date of the month this date belongs to

Answer 1

You can use startOfMonth() function after calculating for 2 days ago date in order to achieve your requirement. Below is my Logic App flow.

You can use the below code-view to reproduce the same in your environment.
