How to increase a list in order to create a Gantt diagram based on date differences?

I hope everyone is well and that you are taking care of your loved ones.

I don't have access to the Analytics extension and I would like to be able to increment a list.

I would like to have a list of the hours [Xo,X1,X2,X3,...,X23] where the values are 0 and that we increment by 1 when the value is between our two dates.

Here is an Example (also in the XLSX file):

We have date (start datetime = 02.02.2021 06:00:00 and end datetime = 02.02.2021 12:00:00)

 The values of X6, X7, X8, ..., X12 are 1 and the others are 0.

 If we add a second date, it is possible to take this list and increment it again. 

Ideally, this would allow us to have a temporal distribution (regardless of the difference between the hours), similar to a heat map.

Thank you in advance for your help.
