can't compare datetime and float values error

Hi all,

I am trying to generate quarter values such as "Q1 2020', 'Q2 2020' etc.

I used this calculation here but i am getting an error that says that 'can't compare datetime and float values'. I tried wrapping the date with float but no values were being generated.

Please see the expressions i used

IF [End Processing] >= 1/1/2020 and [End Processing] <= 3/31/2020

THEN 'Q1 2020'

ELSEIF 

[End Processing] >= 4/1/2020 and [End Processing] <= 6/30/2020

THEN 'Q2 2020'

ELSEIF 

[End Processing] >= 7/1/2020 and [End Processing] <= 9/30/2020

THEN 'Q3 2020'

ELSEIF 

[End Processing] >= 10/1/2020 and [End Processing] <= 12/31/2020

THEN 'Q4 2020'

ELSEIF  

[End Processing] >= 1/1/2021 and [End Processing] <= 3/31/2021

THEN 'Q1 2021'

END
