Running total by weeks including start date and end date

[obuolys123]

Hello, I need to find something like running total but it depends on start and end dates.

Situation:

I have trucks that have start and end dates of working. I need to find how many trucks were working on particular weeks.  Example below.

I have Trucks table with its plate number, start and end date and I have a Calendar table. Calendar table has relationship with truck table on Calendar[date] and Trucks[start_date].  

The main problem is that I can't find a way to calculate all trucks that has start_date less than date of weeks in report.

Do you have any ideas how to count that?

You need to have a week in date table and you need a measure
