Hi Atish_nameunavailable,
your question Calculated column in Microsoft lists
Your requirement may not be able to be achieved as calculated. columns doesn’t support "TODAY" function. TODAY function - Microsoft Support
I found a workaround for you. We suggest you crating tow views named “in progress” and “Completed "displaying the different stages.
For the view “in progress” you can edit it and filter it as bellow.
For the view “completed “ you can filter it like this calculated columns cannot be archive it.
Thank you best regards
