Data calculation while using Date Range

[Kaushik2020]

Hi Everyone, If this is a normal behavior with Qlik sense. 

i am using below expression to get Date range for current month and previous month. 

If I select a month with 30 days e.g-June and Month-1 as July where we have 31 days. below expression calculates month max as 30 only. may be it is due to the Max(Date) function. 

//current expression to calculate current month:

Date={">=$(=date(monthstart(max(Date))))<=$(=date(max(Date)))"}>}

//current expression to calculate previous month:

Date={">=$(=Date(monthstart(addmonths(Max(Date),-1))))<=$(=Date(addmonths(Max(Date),-1)))"},

But i am looking for suggestion where for below condition:

IF Month = June,

{

Month_start = 01/June/2023 and Month_end = 30/June/2023

}

For Month-1 below start and end date should be passed as range.

Month_start = 01/May/2023 and Month_end = 31/May/2023
