Date picker jquery qi

Hi there I am using checkout field editor pro plugin. And I am using Date Picker jQuery ui to start and end date where i want to start any date for ex 1/05/2024 or any date from 2024 which should be after current means not passed dates and according to start date i want to setup end date which will only gives 1 year option from selected start dates.
example: start date 1/06/2024 end date should be 1/06/2025 or before this date like any date before it
if User select start date 18/09/2024 then end date should be before or the same 18/09/2025.

I just need to setup 1 year period time from whatever user select for start date. How to setup in date picker because i have tried to do but not giving me same output.
