I want to display slot duration dynamically for day because we are using fullcalander for booking the volleyball court bases on hours like 10 to 23.

And I want to set the slot duration for 10 to 03:00 for 1 hour,03 to 23 of 1:30 bases on different prices but I am not able to do this.

Use case is this because when we are using the select range hook there is time mismatching for start time and end time due to that i am not able to create event.In the second image i am clicking into 19:00 to 20:30 slot but with select range i was getting 18:00 to 19:00 which is incorrect.[enter image description here](https://i.sstatic.net/4aSRhbTL.png)

I want to know how to fix slot duration issue
