Select specific date from table
Hello there.
I have a column in my query field that is Date type. How could I create another column to be able to take selected date from first date table into the new column. For example I have date range 01/01/2021 - 30/07/2022. I want to be able to select School time off / half term/ holidays (01/02/09/2021, 25/10/2021-29/10/2021, etc.) If I can do it using measures and not creating a column, that`s ok too, as long as I am able to add multiple date periods.
Thank you
Alexandra_B , You can use date table and time filter or both date and time table as filter. Assume date filter is all sorted
you can add time filter on a time column (have or create like)
Time = timevalue([Datetime])
calculate(Sum(Table[Value]) , filter(Table, Table[Time]>= time(8,0,0) && Table[time] >= time(16,0,0) ) )
or use time table to

Alexandra_B ,
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.refer if this can help
Alexandra_B . Sorry not clear to me
Basically I need to calculate data from half hourly fields based on date.
I have created a slicer for days of the week, I will need to calculate the data between 08:00 - 16:00 Mon to Fri for specific dates (when school is open) and then calcuate a different time for the rest of the time.To calculate the data from 08-16:00 for example I can create a measure to sum the fields, then I can select multiple days from the slicer. I woud like to be somehow able to set another slicer/ measure/ column withdates when schools is open.

I was thinking maybe I create another table and create a relationship with the main Date table. It is possible to add multiple date range in the new table?
I now I can do like this :
New Date table = calendar(date(25/10/2021), date(29/10/2021))
but can I add in the same calendar more dates like 20/12/2021 - 04/01/2022, etc?
25/10/2021 26/10/2021 27/10/2021 28/10/2021 29/10/2021 20/12/2021 21/12/2021 22/12/2021 04/01/2022 04/04/2022 It is possible to create something like this , then create relationship with the main Date column?
Thank you.I have sorted it out.
Because I didn`t know how to create a table with specific date from another table, I just added two tables (Home - Enter data - table for School term, same for Half term).
Then, I went to Model to create relationship 1-* (see attached).
After that, I created the visuals I needed, with a slicer representing Days of the week, number of days and other required data. (Please note this is just from the data source I have and it is not complete, if you are checking the count of days 😁 )
I still have to work on design and edit some visuals, but at least I reached the main objective.
Thank you amitchandak for resources!have a wonderful week ahead!
