Show custom Date range based on the value selected in another column

[PRamashe]

@amitchandak @parry2k @Greg_Deckler ,

I have this requirement, where I need to show the Column Header with Date Range as start of the selected month and end date when the current value in another column changes. Also, I have to show the Date Range for the start of the date  and end date as end of the selected month for the new value as well. Any help with the "Date Range" DAX measure is much appreciated.

Example: Below are the tables

Table A		Table B
Rate		Date
0.5		7/1/2023
0.5		7/2/2023
0.5		7/3/2023
0.5		7/4/2023
0.5		7/5/2023
0.5		7/6/2023
1.2		7/7/2023
1.2		7/8/2023
1.2		7/9/2023
1.2		7/10/2023
1.2		7/11/2023
1.2		7/12/2023
1.2		7/13/2023

 Result:

	Code 0.5%	Code 1.2%
Date Range	7/1/2023 - 7/6/2023	7/7/2023 - 7/31/2023
Category	Total Accounts     Total Balance	Total Accounts     Total Balance
A
B

@PRamashe if you read my question, it is not about the rate, it is about the date.

Again question is, one date will always have one rate regardless if it is in multiple rows but it will never be two different rates.

[PRamashe]

@parry2k .Yes. That's correct

[PRamashe]

@parry2k Sorry, I understood your previous question differently. 
Yes, One date will always only one Rate

[parry2k]

@PRamashe ok, one date will always have only one rate? 

[PRamashe]

@parry2k No, same rate will be there for many dates/months. The requirement is based on this. I need to calculate start date and end date for a particular rate in the selected month

[PRamashe]

@parry2k , A and B are related with Many to One relationship with a Date column in both

[parry2k]

@PRamashe how table A and B are related?
