Creare a new table including working days between dates

[DDalmas]

Hello Guys, 

I have this problem where there is a fact table with the a technician _id and the date that he started to work in this project and the date that he finished it.  Something like that: 

project_id	technician_id	date_open	date_close
10001	A1	2020-01-01	2020-01-10
10002	A1	2020-01-01	2020-01-20
10003	A2	2020-02-02	2020-02-20
10004	A3	2020-02-03	2020-02-20

I'd like to count the number of distinct days that the technician has worked. It is a fact that the technician can work in several projects at the same time. Also, it counts all days between dates, incluing opening day and closing day. 

What is the best way to do that? 

Expected return: 
(technician_ID) - (work days)
A1 - 20 
A2 - 19

A3 - 18

Thanks!
