## Days between 2 dates in same table and by month name

Hello,

I have a table that has three columns, one is the person ID, one is the date they entered and the last column is the date they left. I am trying to create a new table on Power BI that calculates the occupancy for each client per month.

I have read a lot of topics and can't find something that works.

I attach pbix and examples.

Thank you very much,

DM

Hi @DM_BI

You may create a measure like below:

```Measure =
CALCULATE (
COUNTROWS ( DimDate ),
FILTER (
GENERATE ( DimDate, Hoja1 ),
&& Hoja1[Departure] >= DimDate[Date]
)
)
```

Hi DM

Does your calculation require "Time" to be taken into account or just days? If not, you can firstly create a calculated column, then create a measure.

The calculated column, will work out the days between the dates:

```OccupancyDays =
DATEDIFF([entereddate], [leftdate], day)```

You can then create a sum measure to calculate the total time spent.

```Total Occcupancy =
CALCULATE
SUM([OccupancyDays])
)```

When you then drag in your person ID and the month into an axis, using your new measure you will see the total time spent.

Hope that helps.

Thanks
